The price increase was when I launched my game Newtraction, over 2 months ago, and it was obviously completely unrelated to this bundle. It was still in the jam state then, and was sold for 1$, had no prize maps, had only 10 levels, so way less than 5 times the content. You can look it up in my devlogs or on the Wayback Machine if you want more proof. Hope that clears things up.
