I really like this game. I think I'm gonna come back and play it more after I've tried all the jam games. I think it was so smart to put the AutoChess idea and Hololive together. You've replaced a bunch of generic characters that I couldn't be bothered to learn (Goblin, Witch, Paladin) with recognizable talents that I actually care about!
I'm definitely interested to see if the other synergies are a strong as blonde gets, I kind of just mowed everything down with ranged blonde units. I was sad to learn that Flare doesn't count a blonde unit, I assume for balancing reasons as they're already really strong.
My only real complaint about it is the text is pretty hard to read for me. My vision is terrible, and the game is at a fixed resolution on my puny monitor. (The big one I'm used to broke yesterday.) So I'd love an option for bigger text. More a "nice to have" than a "must" for a game-jam though.
Oh, and I love what you did with FuwaMoco!
