Can I download Osmos full in both .deb and .tar.gz?

[Dsfargegian]

I switch distros alot, and I'd like to keep playing Osmos.
Hence I wonder if I can have it in both .deb and .tar.gz for just $10? Or would I have to pay $20?
(And is that .deb both 32 and 64 bit? Because I run x86-64 and I'd prefer to run the 64 bit version to be honest.)
And eh, can I later download them from the website (do I get free updates too?!) again if I lose the original file? (Without paying, that is.)

Anyhow, the demo's AWESOME!!
I love it, indie games FTW.

Hi Dsfargegian,

Once you've purchased Osmos, the game can be downloaded in any (or multiple) formats of your choosing, including, OSX, PC, .deb, .rpm, .tar.gz.

The .deb and .tar.gz contain both 32bit and 64bit executables.

Enjoy!

For an unlimited number? I mean I might lose the file!

Do I get like an account to login to and then if I wanna download it (again) I'll just login to that account?
Also: Do I get free updates?
