Avoidster
Avoidster is made up entirely of solid colored shapes, which would make you think it's a simple game. However, it is surprisingly challenging and entertaining! You are the block that is colored differently from everything else. You have to avoid getting hit by everything, whether it is getting shot at you or falling towards you. Do this by using the direction keys on your keypad. However, your shape gains momentum as it moves. That means that it can't stop on a dime or change directions immediately. Getting hit by something will cost you a life. When you run out of lives, the game is over.
