Great presentation: the art in particular was really nice! Interesting weapon variety, and the movement felt good in general.
With that, there were two things I really feel need to be changed:
1. As others have said: set attacking to the mouse button.
2. The hitstop is way too much. It really makes the game feel really stuttery - especially if you have a wand that can hit multiple enemies at close intervals. Use it on the critical hits only imo - this way it creates impact and weight to those. This has been a super common things with the games in the jam using hitstop I've noticed. I think it's a juice element that has to be very subtle and used very specifically to be done right.
I want to emphasize: this game had a TON of charm and I really enjoyed it. I feel that if you fixed those two issues, this game would be very addictive in that Binding of Isaac kind of way. Awesome job!
