Couldn't keep playing for too long, it would always crash at some point during wave 2, probably because I need to use wine in order to play it, maybe you should have uploaded a Linux build? I think it plays nice, the bullets are big and colorful, kiting the enemies feels good, although their AI is to just move in the direction of the player, which makes the gameplay somewhat repetitive. I also feel like there is little indication of what you can go through and what you can't, like, water is the only thing that's okay but everything else always surprised me when it stopped me from moving. I also felt like the game got hurt a little by not having music, but I can understand you, it's a game jam after all.
Overall, I think you nailed the shooting and the bullet hell despite the hiccups above. Good job!
