Eyyyo...
I'm not a dev but I really think you need to work on compressing your game a bit my dude.
6gbs for "0.1" is a *little* bit much, I understand there's a lot of content but many of these games that have been around for months (some, even years) still haven't crossed into 3gb territory.
Now -- I've not played yet (still waiting for the download =P), but as of right now that is my biggest piece of advice: offer a compressed version.
