Use arrow keys. I made this because I'm going to use it for a slope detection game thing. If you press the arrow keys, it will fall at an accurate speed in that direction. Going to make it so you can't just go up as long as you want, but I thought for this project i'd just let it slide.
100% by me. It gave me a bit of a headache. ): It was still fun though. See inside to change speeds (change y/x velocity).
