Slow, boring and annoying
So most people have seen this concept done a thousand times over and sometimes they are done well but this one is not a good one. The game is very slow and boring. The flow of the game is broken every time you have to switch characters. The the different abilities of the characters add little to the game. It would have been a stronger game if you just gave one of the panda's all the abilities and removed the concept of switching characters all together. Also, I have to travel through a large portion of the level with one panda but because the other panda does not automatically follow, I have to essentially play each level twice. If you could make the pandas follow each other it would greatly increase the the quality of gameplay.
