Hallo! Guten Tag :)
I'm sorry to be posting in English, I've been having trouble to find Linux gaming community, and since this is one of the biggest ones, thought I might try to post in here :)
My name is Andre and I work at Kimeric Labs, an indie game studio from Rio de Janeiro. We are developing a game called Satellite Rush, a sci-fi top down shooter with pixel art graphics and roguelike elements.
We're making efforts to make the game available on Linux, and there's an available demo build for download in the project page:
