I can see what the game is trying to achieve but it is admittedly a bit clunky.
When the timer hits 17:59 the game crashes. I speculate that its because your switching the main level scene for a new one which the browser version of the game can not replicate correctly (I could be wrong, I'm not the biggest Godot expert).
Overall, it is understandable that the time constraints led to a lot of clutter and bugs. I believe the theme of Isolation is well-used here and the generator fixing mechanic is a fun mini-game.
