Hello, I'm Andrew, Gunnihilation's designer. Sorry things have gone silent recently, but Robo Pixel Games is shutting down. We've been trying to figure out a way to keep things going but we finally reached a point where we had to admit we couldn't continue.
However, we would still like the game to be available, and are currently looking into keeping the game on Steam for free (although now lacking updates).
Huge thanks to everyone who has supported us and given us their help, advice or feedback, from steam users to youtubers and twitch streamers to the other developers we've met during our travels. It was a fun ride and I'm still proud of what we were able to create.
We will post again once we know exactly what's happening.
And again, thanks everyone.
