Cute graphics. The little bullet particles are a nice touch.
One thing i would reccomend is giving soem kind of upgrade rather than gun from chests, it doesn't really feel like a reward getting the same 4 spells.
Other than that nice audio (all be it a bit loud haha)
I died and gave up since im kinda bad. Would have been better if the path to the boss was linear and short having to kill the same 5 enemies over and over gets boring so either more enemy variation or a shorter path would help.
Thats all my feedback good game overall :D
