Cydia Store! Hilly Billy should set up their game for sale there. Also Zombie Mangle! If they don't want to upload their game there because it'll get cracked. Of course they'll get cracked, they would have been cracked if it was in the app store. Non crack users will purchase your games. Please Upload them to Cydia Store and just charge them what you would in the app store. Or lower. =D
it's available, however if your currently jb'ed and like your set up you might want to wait a sec. Apps that you have for free now may not be anymore. Meaning if you chronically use aptbackup that might be a problem.
