Love the main menu :) It took me a second to figure it out, not gonna lie. I like the stuck in a cassette look- but as Kazeheki said, it is a bit too white. An option would be great. I also had trouble with climbing the wall- I managed to climb it at first, but then got stuck at a high platform I was supposed to jump at. When I tried again I couldn't manage to climb at all. I would have also liked the option of arrow keys besides WASD, maybe I'm alone in this but I'm much more used to them. Overall very nice gameplay and idea, I especially liked that we can aim the rifle. Cool music too- though it reiterates a lot :) With a little polish this will be a very nice nostalgic game!
