We have been working on our game, Dusty Revenge, for some time and now we are starting to show people what we have done. It's still not completed yet, but soon.
It's a 2D side-scrolling action platformer with unique supporting characters. Besides the main protagonist doing the fighting, he has 2 allies, an artillery guy and a sniper whom he can call on to help him. It is to be released on PC and possibly Mac.
We have a development trailer here. Some things have been changed. The video is about 3 months old, but it gives a good sense of what the game is like.
