Very interesting concepts! I had an especially fun, possibly unintended moment where I enlarged to the max while inside a wall and zipped right to the end; but the actual puzzle design was solid. My one piece of feedback would be that I wish the scale of objects to interact with like the box was indicated without numbers on it or the character, but instead with either animations or other texture details. Perhaps some kind of "weak" or "too strong" animation for pushing when not the target size - to keep the screen clutter-free. Regardless, nicely done!
