¨Thanks a lot :) Yeah, even the skills I acquired doing it will be usefull. It took me a day and a half to create the model with all animations, but I started nearly from scratch in terms of the animation part. I knew about the concept of IK but not the whole leg setup in Blender, , didn't know how to setup a run and walk cycle for 3D anims and so on.
I however woke up this morning to my own dumbness and realized why the "moon jump" glitch happens. That's because I used a capsule collider. You can use a capsule collider for a platformer but it takes so much more polishing, I should have gone with a cylinder =/
