Ocean - A Platformer

Instructions: This is my first platformer. Sure, it's just a rip-off of @ElectricGalaxy's project, but this took me a while to make. I changed most (if not all) the art.\n\nUse the arrow keys to move.\n\nNOTE: I hardly EVER view or make platformers - because I am so bad at them - but this one is pretty easy. So if (like me) you think you are bad at platformers, I promise you will feel more confident after trying this one! :)
