I love this!
Small piece of trivia - I made a text based/imagination oriented game about navigating a burning building for the very first Linux Game Jam back in 2017.
I really enjoyed the sense of urgency that the timer gives, and I though the puzzle chain was nicely executed.
I found myself wishing that there were some sound effects for interactions and movement, but I don't think the game is significantly diminished by not having any, and I'm not sure whether TIC-80 games have explicit size limits.
I would love to play a bigger game like this.
One thing to note - your instructions do not mention the need to give the game binary executable permissions.
If you are on Linux or MacOS and had set that before uploading, it's worth knowing that those permissions don't survive when a file is transferred via HTTP. Executable permissions can be preserved inside zip files.
If you're on Windows and can't set that yourself, I made a free tool to help manage that.
