So... is it a platform game then? A shooter? A puzzle game? A hidden object game? Am I going to be playing as a human or a fish or an octopus or a spaceship?
But it's okay because there's also a video which shows ... that there is some 3D stuff, maybe, but it might all just be a cutscene. And there is a ship of some sort, but it doesn't appear to be being player-controlled. Take a tip from Wikipedia, which says in the first sentence "... is a series of submarine-based shooter/simulation games set in the distant future." Still not entirely sure what it's like to play, but "shooter/simulation" conveys a hell of a lot more information than "'Emerald' Dead Eye Flint" does.
