Considering how often it can be found on steam for like $2, it's not very compelling to get. Especially since it's the kind of game that once you did everything you can, it becomes immediately boring... and I've done everything on the PC. I do wonder how well the controls translate, as it's not exactly a forgiving game.
If it pops up on free weekly app though I will definitely pick it up. Not worth the $5 though, for me personally. Especially when you know it's not going to be getting any worthwhile updates, and Starbound is closing in.
