Cool idea! I really like the jump mechanic, it was satisfying to use and utilize to avoid attacks with good timing. I think the curse system could use some work, particularly with what debuffs are applied, as all of them are very punishing and don't feel very good. If you want to stick with the rotating curses, I think it would be better to have ones that just debuff your power in some way (whether they make you deal less damage, move slower, etc), rather than disabling abilities entirely. I ended up rolling the no attack curse three times in a row and automatically died because I needed to keep killing enemies to stay alive. Your foundation is good though, movement and jumping felt very good!
