Ballpoint Universe - Infinite, A Crazy Hand Drawn Action Platformer On Steam For Linux
Sadly this one seems to have been missed, it was released last month for Linux, but as it's not a brand new game (only new to Linux) it didn't pop up as new to Linux on Steam. This is after at the start of last month they pushed out an "unofficial" Linux version for tester.
Ballpoint Universe Infinite is a shoot-em-up adventure game featuring artwork entirely drawn in ballpoint pen. Explore immaculate worlds, discover the secrets of the doodles, and customize your Ink-Ship for battle!
One thing to note is that for some reason the Linux version wasn't able to even get the partial controller support the Windows version has. Although looking further it seems it's not even working with game-pads on Windows right now anyway.
It was originally crowdfunded on Kickstarter in April of 2012, but didn't have plans for Linux back then so it's good to see this happen anyway.
I really wish Steam did bump games up on the Linux section of Steam if they have just pushed a Linux version, it sure would make it easier for gamers and developers.
