It looks like Luftrauser's moved from 4 to 4.5 stars since it went on sale. Hopefully that spurs things along.
Even if is really awesome, 40% off just isn't very enticing. It's fine for Broken Age and other popular games but it doesn't feel appropriate for such a niche release. I'm sure enough people will buy it eventually but it's been like 3 hours so far and I'm finding it increasingly difficult to justify waiting for the games that come after it. They should really just save all of the slow-burners till the very end. Or maybe the could implement a timer that skips to the next game regardless after 20 mins or so. If things continue at this pace, I'm going to miss out on the games that I really want.
