About this update:
Finally, Understand has three save slots.
That's all.
To be honest, Understand started as a small project, I didn't notice it would be a success until the success comes.
That's why it is lacking some features and looks over-minimalized.
Late is better than never.

By the way, our new game, A=B, is now available.
It's basically a Zach-like with some Artless personality.
