Great game!
Had really fun with it, the upgrade mechanic is really good, makes you want to keep playing!
This game basically uses the same core-loop as my game, but as a top down shooter, my game is a platform shooter https://itch.io/jam/blackthornprod-game-jam-1/rate/319341
The art might need some polish and some more effects when hitting enemies would've been nice, but overall a great game!
Amazing job!
