Protonaut is best described as a platform physics puzzler: a platformer covered in a velvety layer of physics, served with a generous dosage of puzzler. The premise of the game is fairly simple: you are a small character (presumably the Protonaut), tasked with collecting all of the gaseous elements in each level. Run, jump, and shoot projectiles to solve each level's puzzle.

Fantastic Contraption is a physics puzzle game in which the objective in each level is to move all red objects into a rectangular goal area. To do this, you are given a blue rectangular building area and a few different materials in which you can build your device. Standing in your way, however, are a variety of obstacles, ranging from gaping gaps to a sea of circles bent on destroying your red-object-mover-apparatus.
