Alex Austin, creator of games such as Gish, Golf?, Sub Rosa and A New Zero, has just released a Beta for his Cryptic Sea EP, which contains three very different tracks to play for $1 a piece. Skate or Don't! is a downhill skateboarding game for up to 8 players, Volta is a "smashing" physics-based action puzzle game (a more violent, electrifying Tetris), and Touring Car Legend is an overhead racer (think Gran Turismo meets RC Pro AM). The Cryptic Sea EP costs $3 in total and is available via the Humble Store for Windows, Mac, and Linux.
