I saw on one of the comments that suggested an autofeeder that you would limit them to three bags so people can't leave their game off overnight and come back to a gazillion coins, and I have a suggestion to prevent it. You could 1. make coins despawn if not picked up for a certain amount of time (around a minute or two i'd say), and/or 2. Make an "are you still playing" popup where it pauses the game every 15-30 minutes or something like that, and the resume button could be in a random spot on the screen (to prevent a macro auto clicking the resume button). :3
