Update:
Note: The event is officially over but you can still donate until March 2nd!
You'll get to see the games once this bundle is over.
Still there are a few builds that one can download, at least 1 for now, I tried a Day 1 build of "Space Hunk(windows only for now)" in wine. Kind of entertaining I think, especially if they add sound in the final product.
0.01 USD symbolic donations are possible in this bundle.
There are lots of people behind these games, and some of them may like a tip of some amount in
BTC if you like their games. If I find anyone whose games I like and I find they accept
BTC I'll update this post

'No reply yet':
Nuclear Pizza War by
Mojang [@MojangTeam] creators of Minecraft, contacted 2013-02-27, contacted through twitter as they don't have any other formal way of contact.
DaisyMoon by
oxeye.se, contacted 2013-02-27, emailed their questions in general section. I just said that I liked their game DaisyMoon(for such short development time I found it quite enjoyable) and that if they are already familiar with
BTC they could if they wish to accept my donation. Otherwise they are free to just accept my humble thanks for helping with the Mojam 2 bundle.
'Of interest':
http://www.wolfire.com/llc features a video(v=UDxxMvY65TI) explaining the game Low Light Combat by Wolfire Games where they suggest at 2:52 "or you can donate to the Blender Development Fund and support and support open source 3D modeling and animation software" (this game has recently been released, at least to my own knowledge, for the Humble Bundle Mojam 2)
