Humble Weekly Sale with Knytt Underground, NightSky, Multimedia Fusion 2

I thought some members of the forum (especially egomassive) might be interested in this! The latest Humble Weekly Sale lets you pay what you want (as little as $0.01) for a copy of Multimedia Fusion 2 and six games made using it, and also offers copies of Knytt Underground, NightSky and Really Big Sky for those who pay over $6.00.

It's not the developer version, so I'm not sure if it will be useful for KS+ maintenance. However, at these prices it's worth finding out. Also, I haven't played KU yet.

I wonder if it would work if you just copy extensions from Dev version. I'm considering buying this
My advice to people who buy: expand the Developers part to set the right amount for Nifflas. Also, set Click Team and Nicalis amounts to 0, they don't deserve it.

So, I bought it and... I can edit KS+ with standard MMF2! This is tremendously surprising. I'm one extension away from access to the level editor's source.
