  2. Due to limited manpower, we are unable to conduct large-scale testing. However, I and a few friends who helped with testing have played through the Demo many times, and it is relatively stable. If you get stuck or experience issues, you can also open the ESC menu and select “Load Last Checkpoint” to reset. Thank you so much for your understanding!

  3. This Demo is currently available only in Simplified Chinese. Due to time and budget limitations, English and Traditional Chinese will be added in future updates.

  4. The game currently does not support controllers.

[A Few Words From Me]

Thank you sincerely for all the support you’ve given me over the years.

This project has been like a seed I’ve held in my hands for a very long time. Since this is the first complete game I’ve ever made on my own, I ran into countless difficulties—but I gritted my teeth and kept going. Still, there were many moments of hesitation and anxiety. Sometimes I even felt like I had lost the courage I once had. Many nights I couldn’t sleep, turning things over in my mind again and again.

But eventually, I realized something: If I never plant the seed, it will never have a chance to sprout.

So this time, I’ve decided to act on impulse—and take a step forward. Even if it isn’t perfect yet, I still want to put it into your hands.

I truly hope you’ll enjoy The Grotto Diary. And I hope your feedback can help make it even better.
