A fellow mancer game! My team made Micromancer which has a similar mage/wizard theme and is a puzzle platformer, I'd encourage you to check it out.
I definitely like the shooting mechanic of sizing objects, I saw another game do that but this way was much less punishing and added an additional puzzle element of bouncing the and aiming the shots. I also want to compliment your programming and physics, nothing got wonky like in our game! The puzzle design was also pretty great and the game was a perfect bite size. I'd have definitely played more!
