Hello,
I've played a game in which you're something like a shepherd with a gun and you had one sheep. You had to keep the sheep safe while hes eating grass from some dark shadowy creatures. In return you received coins and you could buy ammo/updates/lives. It was a 2d platformer, but you were unable to jump. The transportation between platforms was via portals. The graphics were pixelish and there were no fx included. I think it was a some entry for some game jam.
I just went crazy searching for this game.
Any help would be greatly appreciated.
