This is a shooting game with a twist. You are in control of a small character who has to go through a serious of stages. Each stage consists of one screen only and contains several energy packs hidden behind various obstacles. Your goal is to eat up all the energy packs at a given stage, or (which is sometimes easier, but with dire consequences to the later stages) destroy them. If you manage to eat the energy packs, you'll gain more energy points, which carry over to the next stage. You'll need the energy points because every shot from your gun costs you one, and each collision with the various enemies flying around can deplete a large bulk of them.
