It seems like it could be a good game, but as you pointed out, you wanted it to be more atmospheric. The problem is, there isn't much of an atmosphere. You're dropped into the game with nothing explained, nothing pointed out, and some generic (and somewhat messy sounding) chiptune as your background noise. Giving us even a paragraph, or some cleaner - but still chiptune and sci-fi-y- music would help loads. (Sci-fi-y isn't a word, I know.) If you'd submitted this as an art game, I'd give the controls a bit more leeway, but they were dodgy, and it kind of threw me off that you couldn't hit the up arrow to jump. It was a bit fun though! Just not fun enough or atmospheric enough to draw me in for any amount of time.
