Mojang (creators of Minecraft) are holding a game jam this weekend.

What ever they produce is up for grabs via The Humble Indie Bundle site for a donation of your choice, with all money going to charity!

Plus - two other studios have joined in... Wolffire (Overgrowth / Laguru) and Oxeye (Cobalt) - so that is 3 brand new games in 48 hours!

Plus - you can watch the whole process live (whether you donate or not) as it is all being streamed live :)

Pause / Break is blocked by apps running as admin in my PC (Win7 x64)

Thoughts after first brief play session...

Hoard: Only played the 2 tutorial levels and the 1st map, but looks like it could have surprising depth for such a simple casual game. Of the 2 DLC, one adds new visuals only (a 3rd tileset) the other seems to add new maps, a new game mode, and perhaps most importantly several new game elements.

Zeno Clash: Looks lovely, sounds lovely, story is quirky! Combat difficulty defaults to hard and indeed I have died 3 or 4 times in the first couple of fights! I think I personally will enjoy this game more if I reduce the difficulty and concentrate on the story.

Lume: Beautiful and gentle. So far the puzzles are pretty generic. This is created in flash, but unlike Machinarium, nothing has been done to disguise the fact - ie right click brings up the standard flash context menu, it doesn't go genuinely full screen, and if played in a window is cluttered by Flash Projector's GUI.

Not tried the Soulcaster games yet - they do sound interesting but the unappealing graphics are turning me off atm!
