A really nice platformer with simple mechanics. It is kinda cool that you can stomp on the button. I have no questions for level design in the first room because everything is clear with that, but I still don’t know how to fight rats (maybe I had to stomp in timing and a book would knock them. I tried, but it was too hard and I prefer just to avoid them). You should also check the browser version because I wasn’t able to go after the falling platforms.
I also have to say a word about the graphics and sound because in this aspect everything is great – animations, style, voice and sounds. I would recommend you to think about background music to make the atmosphere a bit more creepy, but maybe that wasn’t your main goal and in this case everything is fine.
Overall I really enjoyed this short platformer and I recommend everyone try it.
