So I don't know anything about Bouncy Bob other than the fact that it's apparently bad and it's constantly going on sale. But this seems to be the most insane sale yet.
Basically you can spend a gold coin on Bouncy Bob, and get a gold coin back making it free.
Which brings me to the question, at what point do you see a game that you know will probably be bad and think "well it only costs this much"
I know I tend to avoid bad games that are absolutely free but will ponder on games that go on sale for 50 cents.
