This game will be an underwater endless runner. Playing as a mythical creature you have to swim deep in the ocean away from humans who are trying to capture you in scuba tanks with huge metal claws. The deeper you get the harder it becomes as there are more obstacle to avoid. There will be randomly spawned power ups and items that you can pass over and get. A shield, boosts or time slower which will come in handy when trying to avoid multiple obstacles further on it the game. If you don't pick up any items that give small boosts the humans will eventually catch you and that's game over.

As you swim deeper the background of the game changes.

The score system will be in meters, swimming the longest distance will be the high score.

There will be other characters that will unlock every time you reach a waypoint when swimming deeper.
