Hello, Guynelk.
Thank you for playing the demo.
I’m sorry for the inconvenience with the save system.
I’m planning to add an auto-save feature in a future update.
Also, if you'd like to explore the game more easily, you can press the Home key to enable infinite HP and unlock all scenarios.
If you don’t mind, could you share more details about the gameplay issues you experienced?
Any feedback would be greatly appreciated and will help me improve the game.
Best regards,
Miyoshi Shizuka
