Good game. I was able to beat the first level easy, the second level took so VERY precise movement and was very unforgiving. After getting the two cubes on top of each other, If I was not on top of the second cube when the first was big enough, I could not get on the platform(space was not big enough or collision was too big). it took about 15 tries to get it right. I tried the 3rd level about 4 times, and was not sure how to keep the me from pushing the cube off of the bottom obstacle on the right.
