Played one room. Two of your three notes are bugs I can name, not taste.
The dead clicks: a full-width transparent layer sat over the room. The card's wrapper stays in the layout even when the card is hidden, so the mouse hit that and stopped. Tab and enter worked because keyboard never hit-tests. Fixed: the wrapper no longer catches clicks, only the card does, and all four shelf items answer a mouse click now. Build 1.1.3, verified by pointing at each item's center and asking what is actually on top.
The walk: that one is my copy, not your eyes. There is no walk. The room is twenty seconds, so I took the word out of the page and out of the file instead of bolting on a fake corridor.
The $25: gone from the room. It ends on the room and the copy-the-link button now. The price lives on the page only, where you are already reading. You called it exactly: at the number it stops being a gift, and the number was buying nobody.
On your side: starting DNA, a labeled mutate button and cap becoming slots are the three I would have picked. Say when the slower first minute is live and I will run it again. No review owed back, you already paid with the notes.
