The interesting little puzzle game Wyv & Keep: The Temple of the Lost Idol has just come out with a free preview build for us all to play. I'v taken a quick look at it and it seems quite fun. The game revolves around controlling 2 characters to solve a series of puzzles, getting treasure along the way. Trailer after the break.
You can pick up the preview build here and if you like it can preorder the game for $8 (so like £5?) which also comes with a map editor.
