A game where YOU are the alien

I really don't know if I'm imagining this, but I believe I once saw something about a 2D pixel art driven game where you're the alien on a space station that's crawling through the vents picking off the crew one by one. Anybody know the name of that game?

It's not Space Station 13, that much I know, and it may very well be a failed Kickstarter, but I just can't get it out of my head! Help me, r/tipofmyjoystick, you're my only hope!
