A combination of a Platformer and Tetris? Interesting idea.
The game is pretty good. You did a great job of combining a platformer with the Russian puzzle game. The visuals where also pretty good, along with the music being ok. I did run into a glitch, where a block was placed next to a door, and the player character couldn't enter the door due to the animation. I think you should disable collision while the animation plays, or just automatically take the player to the next level after a set amount of time.
