That is likely, unfortunately -- especially since we've never seen that sort of problem with the iPhone 4 (which has more RAM than the device that tends to have memory problems: the iPod touch 4). Do you ever experience issues with other apps on your jailbroken device?
The other advice I would offer is to delete and try reinstalling the game. If that doesn't work, hopefully the first update will be out tomorrow and do the trick for you. Sorry for the inconvenience! If you continue to experience problems or discover anything else, always feel free to PM me or contact us at email@example.com
and I'll continue to do anything I can to try to help
Edit: I can't provide jailbreak-related support, but some google searching for "apps crashing on jailbroken iPhone" yields a lot of results, some of which seem to have potential solutions, so that might also be a place to look
