I’m glad you’ve enjoyed it ^^ I’m working on the game again so I’m considering your ideas!
Automatic coin collection could be a good idea. collecting coins is meant to be fun and rewarding and letting the coins pile up can be really satisfying to collect them all at once. I’ll think about ways to make it easier to collect coins, or make it optional
Multi-buy is something I’ve added already for the next version! So keep an eye out for the update, I’ll release it as soon as it’s ready.
Thank you for your ideas and kind words <3
