I've been doing this for hours

I don't think there's a penalty for playing one game for a long time!

The penalty system seems a bit ambiguous. I play a game for 6 hours straight without any issues, but I've heard that some games give penalties even after just 2-3 hours of play;; It's quite confusing.

Ooh~! Don't worry, playing diligently isn't subject to penalties. It's the way of the world for consistent effort to lead to fair rewards, so just keep enjoying the game!

As long as you're not just leaving the game on idle, you won't get penalized for playing a long time. Don't worry lol

Yep, thanks!
