Great little game if you're into rogue-likes....or diggles...

Doing this for the promotion, but ALSO this is an awesome exploration/action/crafting game that keeps getting updated. I actually do recommend for coop playing with friends.

Mostly doing this for the steam thing. But this is also a really fun little game. Team based aerial combat with simplistic controls but the actual gameplay is pretty deep with the variety of ships and stuff. I have a lot of fun playing it as one of those games I play in between other stuff. It also has simple graphics so you can basically play it on anything.
