@K_K the currencies are but there are other elements to the game that might be hackable. seems like no one has tried., look at MyCafe, Zahir found a workaround and made a great hack for it. @Laxus has come up with awesome workarounds for server-sided currency games.
Things like these might work for this game:
To change the price of store items (ovens, tables, decor etc) to cost only 1 gem, vs 100, 200++ that they cost now. Crazy amount of rubies”
Open land expansions
Negate tools needed to open plots
Reduce cooking times
To Unlock the store
To make rewards for task have bigger sums, i.e. if a task gives you 50 coins and 1 gem, perhaps the reward could be changed to 50000 + 900 gems. As an example
If doing that for tasks doesn’t work, perhaps the rewards for Game Achievements when you hit milestones in the game
