Image Fight

ImageFight is a top-down vertically scrolling space shooter. On every level there will be enemy ships, turrets, robots, and other machines shooting projectiles or trying to ram you. But there are also power-ups scattered around in small green containers. You must destroy these containers before you can obtain the power-up. Those power-ups include pods that add extra attack power or speed, new kinds of weapons, the ability to fire in different directions, etc. (mobygames.com)
