I liked the puzzles you had that required both shrinking and growing yourself and the other objects. Good job highlighting which objects can be interacted with by making them red against the grey world. I think a little more instruction - specifically explaining how you can't knock over the red blocks - would've been nice since you have to start over when you do. 

It was pretty confusing figuring out what to do and what buttons to press, I couldn't restart no matter what I pressed. Seems like a good start, but better presentation of information is needed. Good Job.
