Good idea and nice art as well but, there is bug with jumping which in game where jumping is key element makes it a bit difficult to progress. Other than even the sound effects for jumping and breaking the wall were really good as well. Also I like the fact that in order to increase or decrease the player size you don't need to keep pressing any buttons and can just drag it with a mouse.

A cute little game! The concept is nice and well realized, but it could be fleshed out a little more with a few extra mechanics or obstacles. The jumping glitch is also extremely annoying and put a bit of a damper on the experience. Overall, a very nice game, keep up the good work!

Loved this! Ill nit pick a few things because they take 2 seconds to fix and I would love to see you fix them.

1) The ground check is off, I'm assuming its too close to the bottom of the square so you can only jump if you are PERFECTLY flush with the ground. That needs to be fixed.

2) You can stick to walls. Quick google "Unity how to not stick to walls" It is just a physics material that you make.

And thats it! Obviously with more time would come better levels but the ones you had were not bad at all, great work!
