This is really great! The randomness is actually very well done: it's an input to what basically is a little puzzle and the one-attack rule makes it pretty uniform! I would maybe like it if the wizards couldn't shoot though high terrain, that would make it more cohesive, but just a detail.
I'm impressed, great job! Sound effects hilarious, as many have mentioned :D.
PS: The cover looks AI-generated, is that so?
