Route overview before you click
The Demo is one dependency chain, so an inactive object usually means the previous duty is unfinished. The shortest reliable order is arrival, two cups, striped-cup puzzle, coachman payment, hidden door key, contract, breakfast, Aldous's bedroom routine, exercise, clothing, and the outside view. Finish each character's dialogue before leaving the scene because several items only become available after the spoken request ends.
Keep the inventory column visible and check it after every pickup. There is no redemption code, random number, or paid shortcut in this route. The only numeric answer used below is 235, and the recording shows exactly how the three portraits produce it.
Collect the two cups and feed the horse
Start Day One and take the carrot

Open the carriage curtains when prompted, let the arrival sequence finish, and leave the coach. Inspect the long planter in front of the house and take the carrot. Give the carrot to the horse so the arrival interaction is complete before you try to send the coachman away.
Take the cup from the house window

Open the accessible house window and look at its grid of dark panes. One pane contains a tin cup, so click that pane and collect the cup into the inventory. If the window only gives a close view, inspect each dark square rather than clicking the frame.
Take the cup from the coach compartment

Return to the coach and open the small compartment below the passenger area. Pick up the second tin cup shown inside it. You should now have two loose cups ready to add to the three already displayed at the other house window.
Solve the striped cups and get the door key
Sort all five cups by stripe count

Place both collected cups beside the three cups at the display window. Drag the five vessels into ascending order, starting with the cup that has one stripe and ending with the cup that has five. When the order is correct, take the coin revealed in the leftmost cup.
Pay the coachman and finish his dialogue

Select the coin and give it directly to the coachman. Continue clicking through his response until he says he will return and the coach drives away. Do not leave this conversation early, because the next required tool is only exposed after the departure animation.
Pick up the iron bar

Look at the grass where the coach had been standing. Pick up the long iron bar lying by itself on the ground. If it is not present, the payment or final coachman dialogue has not been completed.
Lever up the loose board

Return to the long planter and zoom in on the floorboards directly below it. Use the iron bar on the board that sits differently from its neighbors, then complete the levering motion until it lifts. The hidden key appears in the narrow space below the moved board.
Take the key and unlock the front door

Collect the revealed key, select it in the inventory, and apply it to the front-door keyhole. Turn the inserted key and open the door to enter the hall. If the lock only zooms in, drag or apply the key to the keyhole itself instead of clicking the door panel.
Sign the employment contract
Ink the feather and sign

Speak with the maid in the entrance hall and take the crow feather she offers. Open the contract view, dip the feather into the inkwell, and use the inked feather on the signature line. Finish the maid's next dialogue until the game announces the breakfast duty.
Read the recipe and solve the 235 portrait lock
Read Aldous's breakfast recipe

Inspect the note in the kitchen before using the stove. It says to put the pot on the stove, add milk and oats to the pot, add sugar, and heat the porridge. The note gives ingredients and order but no invented quantity, so collect one available instance of each required item.
Count William's five blinks

Activate William Vanderboom's portrait and watch his eyes rather than the room around it. William blinks five times, giving the value 5. Record the value with his identity because the lock does not display the portraits in the order you visit them.
Count Alexandra's two fingers

Activate Alexandra Vanderboom's portrait and look at the hand gesture. She raises two fingers, giving the value 2. Keep this as Alexandra's value instead of entering it immediately into an arbitrary lock position.
Count Aldous's three watch movements

Activate the Aldous Vanderboom portrait and watch the pocket watch in his hand. The demonstrated movement gives the value 3. You now have Alexandra 2, Aldous 3, and William 5, which matches the faces printed above the three lock wheels.
Enter 235 and take the sugar

Set the lock from left to right to 2, 3, 5, following the portraits printed above its wheels. Open the box or cabinet after the latch releases and take the sugar. If 235 fails, replay each portrait animation and make sure the lock's face order is Alexandra, Aldous, William.
Gather the remaining ingredients and cook
The recorded route also collects the pot, milk, oats, wood, a dead mouse, and matches. Give the dead mouse to the cat, then take the matches left after the cat interaction. Missing matches means the mouse-to-cat dependency is unfinished, while missing sugar means the portrait box has not been opened.
Use the mouse on the cat and take the matches

Inspect the low wall opening and take the dead mouse passed through it, then return to the cat on the pink chair. Give the mouse to the cat and wait for the interaction to finish before collecting the matches it leaves available. Search the kitchen area for the wood and oats, and take the small pot from the cabinet area shown earlier in the route.
Light the stove and heat the first porridge

Put the wood in the stove, light it with the matches, and place the pot on top. Add the milk, oats, and sugar as the recipe instructs, then take the heated porridge. Keep it in the inventory until Aldous reaches the breakfast step of his written morning routine.
Open Aldous's room and prepare the morning routine
Match the patterned box and take the razor

Inside Aldous's bedroom area, inspect the circular patterned box. Rotate each patterned segment until it matches the sample marking on the same side, rather than looking for a number code. When all four sides align, open the box and take the razor.
Follow the six-line routine in order

Read the bedroom note: open curtains, wake him at 7 o'clock, shave, serve breakfast, exercise, and dress up. The final reminder says he does not like cold feet, so collect and use the slippers when the routine makes them relevant. Trying to serve food or dress him before the earlier line is complete will leave later objects inactive.
Recover the clock hand and set 7:00

Inspect the toy soldier and the nearby bedroom objects to recover the missing clock hand, then open the curtains by Aldous's bed. Place the hand on the alarm clock and set the long hand to XII and the short hand to VII. The correct display is exactly 7:00, after which Aldous wakes and accepts the next duty.
Shave, clean, and repair the porridge
Shave and clean Aldous when prompted

Use the razor from the patterned box when Aldous asks to be shaved. Continue the grooming prompts until his red ear is highlighted, then use the available cloth to clean it. Complete one request at a time and wait for the next line of dialogue instead of dragging every inventory item onto him.
Use the bird key and finish the porridge

When Aldous says something is missing after seeing the first porridge, put both slippers on his bare feet. Inspect the bird at the window, wait for it to leave the nest, take the small key, and use that key on the top bedroom drawer to collect the berries. Return to the bowl and move the berries onto the visible black dots until the bowl accepts the arrangement, then feed Aldous until he says he has had enough.
Enter the exercise pattern and finish the Demo
Watch the toy soldier, then copy six directions

After breakfast, inspect the routine note and then activate the toy soldier. Watch its full leaning and lowering demonstration before returning to Aldous. Reproduce the pattern by moving him Left → Right → Down → Right → Right → Down, preserving both consecutive right inputs.
Enter in this order
- 1Left
- 2Right
- 3Down
- 4Right
- 5Right
- 6Down
If the game rejects the pattern, confirm that you entered six directions and did not collapse the two consecutive right moves into one. The visual source shows the toy soldier supplying the cue and Aldous copying it, so do not start clicking Aldous while the soldier animation is still playing.
Dress Aldous and check outside

Use the clothing pieces on Aldous after he accepts the exercise solution. Continue his dialogue until he asks whether the guests are arriving, then leave the close view and look outside. The guest-arrival image and the words “To be continued” mark the verified end of this Demo recording.
Fast troubleshooting checklist
If you are stuck outside, check this exact dependency: carrot, horse, two cups, one-to-five stripe order, coin, coachman, iron bar, loose board, key, front door. If breakfast is blocked, check contract, recipe, three portrait animations, 235, milk, oats, sugar, pot, wood, mouse, cat, matches, and a lit stove. If the bedroom stalls, check the patterned box, razor, written routine, slippers, missing clock hand, open curtains, 7:00 clock, grooming, porridge correction, six exercise inputs, and clothing.
The strongest success signal is a new duty or a new item, not a score message. When nothing changes, return to the last instruction spoken by the maid or Aldous and inspect the inventory for one unused item. Do not import solutions from the released premium game into this page because this sequence is tied to the recorded 2025 Demo build.
