A true adventure!
It really seemed like you went out of your way to make something original. I thought this was going to be like the ball games where you fall down to a target. It turned out to be something I thought was a little better. The coolest thing was the graphics. It was fun to see all of these crazy enemies trying to get at you in ways I had not seen before. The hyper sphere itself is very nicely designed. It takes awhile to get used to, but it's still great.
The music is also good and creates tension well. It's really not as fast paced as you would think. Again, I'm more used to playing the ball games by jmtb02 which are just really hard. I'm definitley not criticizing you, I'm saying you're doing well by giving your player an easier time. I thought the trap door was activated by me stepping on the square but it was automatic.
