This is really similar to my other Platformer games, but you cannot control the X velocity (lefts and rights). It's not finished though, I still have to add a lot more levels. Up arrow to jump.
I got the idea from a game called "Space is Key" but a lot of the things (like lava, being able to go up ramps and jump on top of things, change direction, and trampoline) were my idea. We have a brand new level at the end -- it's by far the hardest, in my opinion
