This is Pacman, as played by Neptune. Your joystick guides a barracuda around the sea bed gobbling up green fishes and avoiding octopuses (I haven't counted the legs). Your supercharging (sic) is of course obtained by courtesy of electric eels. Once swallowed, they enable your protege to eat the octopuses (surprised?). The safe period is marked by an audio prompt and the barracuda's green hue: rapidly flashing colouration indicates a return to normal. The maze is more complex than that of the late lamented Jelly Monsters, so the characters are necessarily smaller.

One question: why not choose orange and red for two of the chasers instead of green? And this program does not extend the frontiers of software engineering - but then why should it? As far as I can see, it's a fair version of a much-imitated game which doesn't take aeons to load. If you want a munchperson game it's worth a look at this one before deciding which muncher is for you.
