I was only recently made aware of this board, so I'm a little late on my announcement haha. 

Paper Planet is an Arcade-Roguelike where you play as a moving turret defending their planet from evil invaders. The current version is just a demo however I intend to be very active about working on this project, an alpha version will be out in a few days! Please give it a look if you're interested!
