it's a neat game. but the height of the game may be an issue for people on a smaller screen.
also, i noticed that even after the blocks have dropped, landed, you can still die if you touch the bottom of the brick. i don't know how you could fix that since i also noticed some bricks disappear after awhile.
Thanks for the feedback! This was developed primarily for phones, specifically the windows phone. I will update it in a bit to better fit computers. Thanks again! I'll look in to the collision problems.
