I can defenitely sense a great mobile game with a little bit of polish!
BlockDrop is a physics based high-score, arcade like game where you have to click on blocks to destroy them before they reach the top of the screen.
The Controls are easy, just click (or press space) to destroy any blocks that fall. Also, if there are power-up blocks (only in Pain mode) click them for some fun explosions or blackholes. (Notes: On the main menu you click on the block next to the words to select that game mode.)
