Really fun and creepy little concept, the idea of tetris on a horizontal plane with enemies that can hurt you is pretty novel and I really like that. Found the controls relatively unresponsible and unreliable, moving diagonally didn't always work and often left me in a bind stuck in the corner. Really cool little soundtrack and sound effects, great effort, well done!
I think the game would have benefited from being just a few tiles bigger in all directions, the size of the tetris pieces made the controls difficult to navigate around.
