Pretty good game. Like what you did with the 2 dimensions. Took me a minute to notice that I was actually switching to different worlds, at first I thought I was spawning in a block and a tree lol, but then I noticed what was going on by the time I got passed the first ghost. That's good enough, it's hard to get people to understand how your mechanics work. Oh you know what would help, slightly different colors (even a tiny brightness/hue adjustment) probably would have conveyed 2 different worlds much better
