Beat the game, it took me a few rounds to understand what was happening but once i did I kinda really like the idea. An auto battler where you level your characters to win harder is a great game. I like how you handled the upgrades for Marni and you should keep that and expand it for sure. I think that maybe having the shape of the general magic that flies around everyone should hit more though, instead of the 20% chance they have now, maybe change the shape so theres a 70 or 80% chance to hit enemies. Enemies can have a shitty shape at first but it gets better and more likely to hit Marni as levels progress.  Changing the colors of your bolts or the enemies bolts is a must as well. Also multiple enemies and different allies with different attacks/patterns would be kino. Overall I actually like this concept and gameplay a ton and I would love to see you continue and make it great.
