An expansion of the dogfighting turn-based strategy hit, SteamBirds: Survival, focuses itself on October 15th, 1940. You must do all you can to hold off the Axis forces over the city of London so that civilians can evacuate. There will never be a victory parade since your defeat is assured, but you will want to last as long as possible all the same. Choose your plane, and Godspeed.
A turn-based aerial dogfighting game may sound bland in writing, but as SteamBirds conclusively proves, it's the whole nine yards of awesome. Working from a top-down perspective, you fight a series of increasingly difficult enemies with your small squadron of planes. Set your course, unleash a fancy ability if necessary, and try to maneuver yourself to a direct line-of-sight to your foe to set your guns blazing. And, you know, don't get shot down yourself.
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.
