Atmosphir is a free platformer game / design tool hybrid for Mac or PC. Designers can create huge 3D interactive adventures, and then share them with an online community.
You don’t have to be an expert programmer - building levels is as simple as selecting blocks (such as a sand castle tower, fireball-breathing bird, or trap door) and snapping them onto a grid. With intuitive controls and low performance requirements, anyone can play, design, compete or collaborate.
