Hi Mark, thanks for your feedback.
Yes, if you don't enjoy resource challenges, Sandstone won't be your cup of tea. If your hands cannot yet break granite, you've simply missed a sandstone block somewhere on the Act 1 map, and if you haven't broken granite yet, the story has hardly begun.
Could you clarify your 'get 99 balms' comment? There is a single balm available in the scenario you outlined, but not 99. I double-checked the project code and it looks correct.
