I tried liking this game, but I can't. I played on chill because "normal" was too frustrating. I made it to lv 16. The game is a frustrating mess of dealing 1 or 2 damage until I win. I may suck at this game. I don't want to be good at it. I love the concept and the music and the art. the game is not fun. I feel powerless most of the time. David fighting three Goliaths at the same time. I wish I had more control over the game.
Thank you for trying and I am sorry it gave you a rough time. People are finding the game difficult and I think it is a mix of high health enemy groups and the fidelity of drawing circles making it difficult to deal high damage.
It might be worthwhile that I look into alternate tools/ ways to attack for the player that still resonate with the game so there are more options for the player to fight back in addition to nerfing many of the levels. I appreciate you sticking with the game to level 16 and can understand why the game would get frustrating :)
