Bubble Trouble is a retro game that is simple, yet challenging. You as a player (up to 2 people can play) have these bubbles that bounce through the game area, and you must avoid them hitting you. Bursting bubble yields smaller bubbles that are more challenging. Use your left and right arrow keys to move, and your space bar to deploy the hook-chain thingy out of the top of your head.
I remember another game named the same several years ago, but in that game you did not dodge incoming bubbles, but shot them with an arrow thing. Definitely not the same game.
