Boring but no ads

It would be so great if there were no ads, it wouldn't interrupt the flow! Is it a game with a certain charm that makes you keep playing even if it's boring? It makes me curious about what kind of game it is if you can forgive it to that extent!

Hmm.. I'd suggest trying it out first.. because there are hidden things one after another. It's a bit awkward to explain ㅜ.ㅜ
