Yeeees! Love this. Pick-up-and-play, no unnecessary confusing mechanic fluff, just simple to understand with plenty of opportunity for depth.
It'd be interesting to see more enemy types, but the game as is is really good. I guess I'm not entirely sure how I healed - since I seemed to, every now and then - but this game is super solid.
Love the art too. Looks very clean and matches well with the UI elements!
