A neat concept; though the bugs are quite numerous. For instance, you'd frequently drop items by moving the mouse in just the wrong way; or otherwise you might push yourself into a wall and either fall through to the void or else get stuck for all eternity  (or until you hit r). Overall, well done.

The game has a nice concept, but has a few bugs that make it quite difficult, for example, I accidently fell through the world and had to restart. Nice music too!

I really like the overall idea of resizing Objects within the level in order to progress (used it in my Game too haha)

But be sure to remove all bugs that make the game unplayable, for eaxmple when i resize or grab an object, i get reset to the beginning of the Level.

Player Movement is nice but please put jump on space (only my personal opinion tho)
