I'll PM you to compare links if you let me know which direct downloads you have. I already have all this stuff so not like I am going to swipe anyone else's.
I'm pretty sure Gala just has one dropbox account though and not that they are generating unique urls for everyone or anything like that. I know the developer of Smooth Operators mentioned he noticed a huge jump in his game being pirated after Gala put it as a DRM free direct download via dropbox in one of their bundles. He made a special edition of the game just for Gala and that was the version being pirated.
Ya that sucks. It's pretty sad people still pirate games, especially from a freakin Indie Bundle when the games are already cheap as crap.
