Excellently done on the polish and effects aspect, especially the effect when the player dies. I have a few recommendations: 1) Having more enemy variants would go a long way, even if they are really simple and you have to take shortcuts in other aspects 2) The difficulty curve might a bit wonky, ideally the difficulty should remain the same across the game, the current system you have only makes it easier which does not give the player an incentive to keep playing 3) Maybe make the camera size bigger so we can see more things at a time. Anyways well done on your first game jam, hope to see you in upcoming jams as well!
