[Release] Pre-Alpha 0.0.0

First ever release of the game.

This version has:

• A basic map editor.
• A couple different tiles.
• Water and lava.
• 3 different powerups. (fire, poison, freeze)
• 2 extra abilities. (decoy snake, temporary speed boost)
• A single enemy type.
• Treasure chests that you can put coins in, or just leave empty.
• A door that, when touched, ends the level.

It's pretty obvious why this is just a pre-alpha, right? But there's more to come!
