The Adventures of The Lost Spacesheep, Destroyer of Universes
A downloadable game for Windows
SHOOT AT THINGS
ENTER THE VORTEX
Adventures of The Lost Spacesheep, Destroyer of Universes is a short shmup where you'll follow the long road through the multiverse that a Spacesheep has to travel to finally get home.
On a serious note: The game has a lot of rapidly flashing high contrast colours. If you have any health problem that could be affected by stuff like that, I really suggest you to avoid playing this game.
