Simple but very good and fun. Love the procedural generation, the art and the music. Punching using the mouse felt a bit unintuitive. In fact I completed the game with keyboard only before noticing you could punch. I was also going to comment the field of view was a little to small since I kept running into enemies, but then I saw it was zoomed out in one of the screenshots (I didn't think I'd have to read the tutorial!). It would probably be more intuitive if it was a keyboard only game.
