The combat and and art style / presentation is really enjoyable. I'd play it for easily 15-20 hours, at which point the asking price would be well justified.

The problem is that you're done after two hours. Sixteen levels just isn't enough, especially if many of those aren't so different in the first place.

Devs, you've made a really good game - please give us a way to play it beyond the initial honeymoon stage.

(If you don't want to go back to level design, maybe community hub integration is a way to provide content for free?)

I didn't post this as steam review because it requires you to give a recommendation whether people should buy the game, and that didn't feel fair either way. Hence this post here.
