Hey, that´s a pretty neat idea! I know you made it in a short time, but here are some tips for next time that make your game much better:
1. Use WASD next time, especially if you also use the mouse.
2. Use a different background color then the standard one, just seems more proffesional.
3. Have some kind of way that indicates that you finished the level, just a text that says "YOU WIN!" or something.
4. I could see this expanded out to a full game, and i wish you worked more on it. Also the idea with the player attached to objects is amazing.
I don´t say it often, but this game really has potential and i really like it.
I made a little platformer in Unity too, would be nice if you checked it out. :)
