I encountered a bug in this area: once I triggered the enemy battle, it hang.
The console output looks like this:
Other than that, you weren't kidding about the game being unbalanced! If Marni manages to survive, she starts balling out of control quickly, and I wanted to keep playing so that she could get even stronger, but I got stuck in one of the levels: the path ahead was too narrow to walk, don't know if it's a bug, or the level is just unfinished, and that's why it's like this.
On the other hand, it feels like I have 0 control over the game, cause all spells are cast on cooldown(although, some of them weren't cast even when they were off cooldown, I even tried clicking them, but it didn't work, don't know what's up with that), and Marni's speed is too slow to really affect anything(reminds me of SNKRX, t had the same problem).
Oh, and I liked the art.
