I have now some project of Stitch!
I have started it, and here is some screenshots and first demo of movement.
(Game will not contain those trees when I publish it, I am just testing it. )
Game has currently perfect anti-moonwalk, and room based engine.
Controls of demo:
Arrow keys to move, up to jump, up twice for double jump.
Give me feedback and some ideas!
(Stitch's animations aren't my own made, they are from here: http://sdb.drshnaps.com/display.php?object=2734)
