This little puzzle game for a break, although created with Gameguru, isn't a first-person shooter. Quite the opposite. It's meant to be reminiscent of a vacation by the sea, where you can truly relax. No weapons, no enemies, except for a few small crabs that might give you a little niggle. They're harmless, though, and easy to avoid.
Since it was created with Gameguru, please, before you curse it for that reason, give the game a chance.
