Cool game for this jam! I like the visuals and gameplay, but there could be even more juicy particle effects tho.
Now, about some flaws.
Sometimes bullets fly too far from the cursor. Also you should restrict space where player can walk, so it would be more challenging and fair. Music should be more cheery and exciting to keep player engaged. Also font in "how to play" is kinda unreadable, but maybe it's just me. Make the game more balanced and fair in general and it will be perfect!
