Here are the game creator's notes on the demo (quoted from his patreon account):
"Do not forget that this is just DEMO, and not a complete game. But only the beginning of his journey. From now on, an update will be released every 2 weeks.
1. The game is only partially translated, and the languages in the game may be confused. The translation of all languages was done through Google translator. I apologize in advance.
If there are people willing to help with translations, I will be only glad :)
2. The game has quests that can start, but they have no end. The game may have combat that can give an error. The game may have mini-games that also may not work correctly yet. Please understand and forgive me that the game is not finished yet.
3. I will accept any criticism, advice and help. Just please no insults.
And lastly, I want you to understand that this is our first project, we have no experience. We learn from our mistakes, but what I can definitely promise is that we will finish the game. I hope someone will believe in us."
