Yes, that's what you heard. I's going to be fully commented and easy to use and expand. It comes with three dimensional movement, events such as "onJump", and a demonstration that you can play and learn how to use this system.
It's going to be called "JUMP ENGINE". If I suceed to finish it, I'll release it on the Store. But if I get enough support from the community I may release it for free, who knows?
Acceleration/Deceleration on px and py axis are working fine. And the jumping system is working as well, with a very HIGH customization, letting you even set the number of possible jumps to any number you want! (Like, more than 2).
