Here's a bug with Demo 16. Upon choosing the option to surrender to Lily, your character's stats and current equipment will be completely wiped and reset as if your starting a new game, but your current progress and the items you had in your inventory will remain.
Edit, this happened specifically when I chose to encounter her for a second time.

In level 5, a VR Headset will appear. If you choose to take it and sell it, an agility check will occur. After passing the check, you will obtain it. Then, save the game, exit to the main menu, and re-enter. You will be surprised to find that the VR Headset has reappeared.Therefore, you can repeatedly refresh and retrieve it by repeatedly using SL. Even if the agile check fails, you can re-check it using SL.A VR Headset costs 25 Gold. This bug allows you to repeatedly farm money.
