I love games that try to use only the mouse, it's especially fun for gamejams and fit well for this jams theme. I had a little trouble as the others below mentioned with judging the distance but I got the hang of it after a few tries. Probably some kind of indicator of when your attack is "fully charged" and it's correlation to the distance you travel would add a lot to making it clearer. Good work and I'm glad you're planning on continuing with this one!
