Reveal the four question-mark cards, open the keypad at the right door, and enter the password 1305.

Layout: The room has a flat grey-grid floor. Mr Potato starts below a row of four question-mark cards, and a chained arched door waits at the far right.
Goal: Reveal all four cards, enter 1305 on the door keypad, and walk through the opened right-hand door.
Opening: Use short jumps from below the card row, adjusting left and right so each question-mark card is touched and revealed.
Danger Zone: Approaching the chained door before the card sequence is complete leaves the password step unfinished; do not close the keypad overlay before entering all four digits.
Mechanics: The four question-mark cards are reveal targets. After they are activated, the chained door presents a four-digit keypad whose verified password is 1305.

Finish the four-card reveal before moving right; the keypad is the second stage of the level.
Enter the digits in order: 1, 3, 0, 5.
If the board feels stuck, look for the color with the cleanest path and use that to regain space.

Stand beneath the row of four question-mark cards and jump into the first card.
Reposition horizontally between jumps and touch the remaining three cards until all four become revealed blank cards.
Move right across the floor to the chained door to trigger its keypad overlay.
Enter the password digits in order: 1, then 3, then 0, then 5.
When the display reads 1305 and the chain clears, move into the open door to trigger victory.

Walking directly to the chained door before revealing the cards skips the required first stage.
Entering the initial 0000 display as the password is incorrect; the demonstrated code is 1305.
