This is an interesting platforming engine I made with 23 example levels for you to try it out on. You will slowly gain momentum as you move and if you have too much momentum you could keep going after you stop pressing the arrow key. In this case, hold the opposite arrow key until you turn around. If you fall from too high you will die. Hold the up arrow key to fly. Pink is like an elevator. When you touch it, it will make you automatically fly. Light blue kills you, and dark blue forces you downwards. If you touch red you see that your cape disappears and you lose the ability to fly. If you find yourself in a situation where you have to make a large fall, while you are falling occasionally tap the up arrow key so you don't fall as fast. I know it's not the best engine ever, but feel free to remix and use different parts of my scripts. There is currently no ceiling detection so keep that in mind as you use this engine.
All scripts, art and sounds (there aren't any) are by me.
