Playing it now I agree, the spawn times are far too low. As far as expanding, I would like to add a chance for gems to have hidden powers that add more characteristics like explosions or piercing shots. The skeleton of that is already in the code. I would also like some sort of meta progressive that involved getting gems and ingredients home and brewing potions that gain effects permanently.
Yeah, I ran out of time for the final UI polish. I wasted to much time trying to fix dungeon generation, instead of giving up much earlier and just making a static floor. The player being slow is likely due to there being a slight pause when shooting, this was intentional but probably feels much worse than I anticipated
