I actually really enjoyed the game, and was disappointed that it was so short. I was hoping for a couple more worlds. I guess they did good though. Hook you in with the gameplay then hit you with the black mirror shtick and get out before it can get tedious. Always leave them wanting more.

I want more.
The Chao racing from Sonic Adventure on the dream cast. You could take the memory card out and use it as a tamagotchi to care for the little guy and make it train so it gets faster and stronger in the real game.
It got no better than that.
