Hello, I'm the creator of , 7757.
There is an error in the current game where the Steam achievements is not achieved properly.
I am having a hard time fixing it because I haven't found the cause yet.
As a temporary measure, we've added space to identify achievements in the in-game gallery.
The achievements are not recognized on Steam right now,
When you run an updated game after the error is corrected in the future
Achievements achieved will be recognized at once.
In addition, the image was changed due to duplicate answers in Chapter 3 puzzle design.
I'm sorry for bothering you.
Thank you to all the users who are playing.
