There is no shortage of amazing indie games available on the PC and it is possible that Grimind could be added to that library. Grimind is a puzzle 2D platformer, with an interesting creepy/horror vibe. At first glance, it does not seem like it but it is very creepy. Grimind is also featured on Steam Greenlight here.

The game may not be available yet, but if you purchase it now you could get access to the beta and if it makes it onto Steam you will be given that version as well. If you would like more information about the game or try the free demo head over here.
