I like the concept of deciding what stats to pick to make sure you win, though I think the layout needs some work though, since I didn't realize the green and white sides were separate options until after the first fight.
I think how much a stat lowers or raises should also be shown? It feels unfair to pick something that gives both sides health only to have it give the enemy more health than you.
Still a good game overall! It's fairly polished, and I like how there's a toggle to turn off the post-processing.
