There are one physics-platformer template-asset to purchase on Scirra's store, but I wasn't convinced with it. I also tried to combine a platformer-behavior with the physic-behavior into the sprite-object, but it does not seem to work well: Walking on the solid objects or jump into them below works not well.
Could a Scirra's team create a working physic platformer tutorial for the users? There is couple of topics on the Forums but having no clear and working solutions. There already is a platformer and physics -behaviors in the engine for use, but who can be sure they really work together, with easy or/nor by the hard way.
For example my game concept requires a solution to create a simple 2d-action Puzzle game including some jumping-/ and ball shooting elements.
