I really love the art and post processing. Reminds me of old school flash games.
Definitely potential here with some more levels and adjusting some physics things. Often if I was on top of the block in the last level it would just roll around with me.
I also noticed the numbers indicating your max/current scale will max out when you get a new pickup, so that was a bit confusing for me at first trying to figure out how much scale I had left.
Overall nice entry!
