Platformer Tutorial

Game by Frederick Smith.

For my proposed modifications, I want to add at least 5 levels. I want the levels in question to be very open ended; almost like a metroidvania (In form alone).

I want to add some kind of genuine powerup. Failing that, I want to create a new type of enemy. Perhaps one that follows the player.

I want to add a boss fight that is more complicated that just defeating a regular enemy with slightly more health. I'm not gonna pull an Icarus and make any wild claims, but I would at least try to set it on a moving platform. Possibly also give it a projectile attack.

This game is controlled using the WASD keys for movement and the space bar to jump. 

If using a gamepad, then the left stick is used for movement and the right trigger to jump.
