A pretty solid first game! I love the glow of the objects and the background is nice as well, the art is simple yet effective, and gameplay feels nice. However, The player seems to shoot slightly off from where the mouse is pointing. Enemy variety is also not that much and I don't really find the chaos in the game? Other than that, it's a nice game. Keep it up! Hope you can learn more from this jam!
Edit: actually I found out about the chaos part, maybe add an indication on how to do that in-game? And definitely make the window size a lot smaller for the web game.
