Thank you so much for your great feedback !
I've been adjusting some aspects today and I increased the speed and decreased the couldown of the fireball.
UI has some issues in the web build, I don't have those issues in my editor so that's weird, I'll try to figure it out
Spawning definitly need more polishing but I need to work on new enemy types and new spell first otherwise I'm afraid I won't be able to finish the prototype before the end of the jam.
Thanks again !
