Nope, it wasn't originally a space-cat game. Just sort of morphed into one after struggling to come up with an original name. My wife just said something to the effect of "mewwwn base" - and we both thought a space-cat would be amusing. Certainly gives it at least a slightly interesting differentiation from just "your a little cartoon dude on mars".  

Steam release, will update the FAQ soon once there's more progress on it.  Been pretty busy past few months, just haven't had the time to get that ready for public release yet. People that have already bought the game on itch will get a Steam key for it as well.

Perfectly aware that it's DRM free. In my opinion that's one of the great things about buying games on itch.io. It's up to the players to make that kind of judgment call as to what they do with their copies. Sharing with a family member, totally cool in my book. Sharing it with every one of your friends/classmates/collages etc, less cool, but it's up to you where to draw the line. As the developer, of course I'd prefer everyone buy their own copy of the game if they're able to :P
