This is the game I made for my first Ludum dare, MetaShift. The game is basically you trying to survive. As you eat food you can build up fat and use that to transform into another creature with different traits.

The controls of the game are very simple, just the arrow keys and the spacebar. The game mostly explains itself but to make it clear:

Spacebar -> Menue selection and action button
Arrow Keys -> Menue navigation and movement buttons

Also, the circles at the top represent various stats as follows:

Red -> Health
Blue -> Food/Hunger
Navy -> Stored Fat

Also behind the coral, you can hide and predators will stop chasing you.

As a final note, on the left edge of the game environment, there is a strange collision bug where you get stuck there, to get out tap the right arrow button and wait for a few seconds then try to get out and repeat till you do get out.

That's all and I hope you enjoy the game.
