A pretty good challenge.
I thought this was an interesting game because it stretched you mind. The rotation controls made you think and plan out your moves ahead of time, it required a lot of logic. The animatioon and controls were nice. It took me numerous tries on the death block levels, but I still thought this was an amusing game.
I recommend trying to add some new features to it. I've seen several games that focus on the concept of rotation and gravity, this really wasn't to different. The teleport blocks and doors were creative but it started out way too slow. If more creativity is expressed, the replay value should definately increase.
This was a enjoyable game. It became repetitive at times, but the online feature was fun to use, I am definately going to send some levels to my friends. I'll recommend this to the puzzle games collection for you. Keep up the great work!
