this game is probably the best i've seen in the jam so far. the visuals are done really nicely, the enemy types blend well with the game and honestly it's really fun to play. i'd recommend making a web build of this so more people could play this because this is a criminally underrated game for this jam.
some things you could add to the game could be screen shake to make shooting feel more powerful, and a dash that could kill enemies to make for some brutally fun gameplay.
all in all, a fantastic game.
