Chris Read, aka atari2600land, works on a new Game Boy game called ten pest.. It’s a shooting game where you’re in space and shoot different UFOs coming at you. You’re on a fixed Y axis, but you can move around the X axis by pressing left or right. Pressing up and down changes the position the ship is facing. The aliens come from the bottom or top and move towards the center. The object is to not make them reach the center of the screen. Also, some UFOs shoot at you, so if you get hit by a laser, the game can end that way too.
