Application coding/altering

I downloaded a game called True Surf on our iPhones. The game requires me to play countless hours before getting to a better board that feels like surfing.

I would like to enjoy simulating my favorite sport with no progress. I tried doing the glitch for unlimited shells the in-game currency, but it was later patched. Being a new and less known game there seems to be no cracked version from Tutuapp or similar.

If there is a way to get unlimited shells without jailbreaking my phone, it would be appreciated.
