UFO 50

"UFO 50 is a collection of 50 single and multiplayer games from the creators of Spelunky, Downwell, Time Barons, Skorpulac, and Madhouse. Jump in and explore a variety of genres, from platformers and shoot 'em ups to puzzle games and RPGs. Our goal is to combine a familiar 8-bit aesthetic with new ideas and modern game design sensibilities."
