Needs Some Work....
The game is a good start and has loads of potential... However with a a little more polish and time it could become a great game. Heres a couple of ideas that could help....
GRAPHICS - Well it's a block and lines.... Maybe use a sprite character or a character of your own other then a block for starters. A background of some sort would definatley be worth while and preferably not a solid colour. (2/5)
SOUND - Well there was no sound or music to speak of... Adding sound effects or music would definatley be a plus. (0/5)
PLAYABILITY - The game itself was a good premise and had a certain degree of platfroming difficulty.. So i'm giving it full grades for this category... (3/5)
I gave you a passing score to help you through the portal, and i hope that my review helps you improve on this or helps you in a future creation.
