Enjoyable little platformer! I want to say night job first of all. I wish there was some background music as the world felt a bit empty without it. I also would have liked a bit more progression so I felt like I was working toward something. There was a stretch were all I got was HP up and didn't see a boss for a ton of doors. Then after the boss that showed up I got nothing but HP down for a long time. The controls were nice if not a bit floating and I wish you had a key bind to open doors rather than clicking on them, but overall wonderful work.
