I'm not familiar with unity so I can't give solid advice but the controls are impossible to use, on the stage after the first key meaning where you are a ball with the padlock the way the platforms line up you can't see where you a going.

I managed to get soft locked by grabbing the key first on the area with both a weight and a key.
After getting the weight second, to reveal the pad lock ,the key was gone and I could no longer finish the game.

Really like the overall concept and thoughts gone into this game. I would suggest that some of your movement control really needs some work to 'feel' great, when dealing with jumping onto platform you overall really want to avoid the 'floaty' feeling.. to avoid this I ramp up the gravity and make the movement input ramp up quickly or just go from 0 - 100 on speed.. no build up, this can give your players more control and avoid frustrations.

The game itself didn't seem to share any 'stealth' themes and if you are submitting games to different game jams then good on you :) but do try to incorporate some aspects if possible :).

Keep up the great work though! the concept was great idea, just needs some movement and level tweaking to be a classic :) 

Neat idea, but extremely difficult to control your character.

Not really stealth game, but the theme was optional I guess. I like the idea of turning into objects with different physical properties. The controls are impossible though. This game needs precise movement and the controls are the opposite of precise, making it way to hard
