Thanks so much for your comment! Do you mind if I dig deeper?
Regarding the controls, did you play the 'practice' mode? It's meant to be a tutorial, but either the tutorial is bad, or the name needs to be 'tutorial' rather than 'practice'. Just wondering which one.
The de-spawning is more worrying. The AI did very occasionally fall through the floor in my tests, but it was so rare that I didn't fix it for the jam. Does it happen for you every time?
