Matchbox Battery are a six member team of students heralding from Brisbane, and they've been developing a 3d puzzle / platformer "with a bit of a twist" for the last six months which they've just made available for play on their website.
The game, Scrapped, was developed using Unity and looks to be partly inspired by Valve's Portal in the way that you've been provided various kinds of guns, or arm extensions in this case, that perform specific functions, and it's up to you to figure out how to use them to solve some tricky puzzles to progress through to the next section.
The arm types and the puzzles and are quite creative, and overall it's a whole lot of fun. If you have some minutes to spare, give this game a shot and send some comments and feedback to the folks at Matchbox Battery!
