It seems like it's going to take an awfully long time to earn enough coins to buy much of anything in this game. Am I right in noticing that coins don't accumulate on your pets over time if you don't collect them for a while? For example, a pet that earns 10 coins every 5 minutes doesn't give me 60 coins if I wait 30 minutes to open the game & collect right? It only gives me 10. That seems to be what I'm seeing.
