Yes it's the beta mentioned here. Anyone who signed up will get full access, we're just waiting on getting more Mac/Linux builds for me to put up!
I can't 100% say what will happen with reference to Steam. We want to do the right thing, it looks like we can do the right thing, but I can't definitively say right now because we don't run Steam! For now, the only Steam version is the original Eufloria on PC.
Anyone buying the bundle version will definitely get full updates when we release the final versions on PC/Mac/Linux. This will not be until Spring or Summer next year because we have Eufloria Adventures to finish first. This is a useful test of our core ports and a chance for you to play the PS3/iOS build on your computer, and then we'll improve them before they go on general release.
Anyone who already has the original Eufloria; well see my first line. Alternatively, we've worked really hard to keep polishing Eufloria, you can pay whatever you want for the bundle version, you get loads of brilliant games and support charity. It's not a bad deal!
If anyone really really objects to paying anything for the above and just wants a pc, mac or linux build, well PM me. If Alex or Rudolf say yes I'll get a build to you. Ok? But after we've had some rest.
