Thanks!
You'll be glad to know that I'm actually working on expanding this one right now, and am expecting to release a more fleshed out version within a couple months. I'm keeping the smaller arena fights setup, but with a bunch chained together instead of just one really long one. I'm also introducing a kind of "passive traits" mechanic to add some more diversity to the run throughs.
Would love to hear your thoughts on it once it's released :)
