bug fix

Thank you for playing CleanCityProject!
This is ritoharito, the developer. We have made the following updates

Auto-save support: The game will automatically save every 3 minutes.
Fixed a bug that prevented users from unlocking achievements while playing.

There are still issues with glitches and lack of user experience, which we will address as much as possible in the future.
Please feel free to contact us with bug reports.
