By selling a lot of copies AND putting barely anything into it. Super Hexagon is bereft of actual content and actually has very little actual game in it. It is a perfect example of how to make money from not much work.
Super Hexagon has highly polished gameplay and a stellar soundtrack, not to mention being very, very fun. IMO Terry Cavanagh knew exactly what to leave out.
We don't do that, though. We put AAA polish and content into every title.
