v0.18d
This update fixes almost all known bugs since version V0.1, making it a stable version to play. However, due to limited manpower, there may still be some bugs we haven't discovered. You can leave feedback in the comments section of this post or join NLCH's Discord server. We'll fix any issues as quickly as possible.
Please note not to use old version save files, as this might cause old bugs to reappear. For your convenience, you can now hold down the ALT key to play the game at three times the speed, but be aware that this feature might make the game unstable, so use it at your discretion.
