It was quite hard for me to understand this at first. I am glad I realized that you could move in depth with the letter keys. It's still pretty difficult, but then again, I did go on hard mode. I really liked all the little details that were in this. It gives you a good sense of being off in a strange world. I always liked games that made their own worlds.
I had no idea jumping at the screen could hurt you. Didn't get much of a high score. It's still very playable. The sounds and music are done very nicely. I just now realize it's in a cube. Thank you for this inventive game.
