Fun idea to have puzzels with the clones. I did get a bit confused every now and then with the walls. Sometimes I could walk behind them and some times I just didn't quite realize where the wall ended and the ground begun. This also caused me to be stuck on the first box for some time. I also feel like the selecting of a new clone could have been a bit easier with a larger range. Last thing that I would have liked is that there were some checkpoints.
Other than those things it was a great entry and the game has some fun puzzels.
