I want to thank you for making such a nice game! I don't know why, but as soon as I saw this game, I immediately knew that I would like it. Although I thought the game would be at least a little longer.
I would like to suggest making some of the "game endings" have some kind of premature alternate ending. For example, when Annette went to bed or left the house, you could add another picture or at least write a couple of lines why the game ended (when Annette left the house, I still did not understand what happened to her).
Otherwise, I really liked everything. Thinking about what to do to go further and explore the house was very interesting. It was nice to spend the evening with Annette looking for her brother.
Thank you Eru-nee and good luck with everything. This is very good for a first game (I'm really looking forward to the new version of the game!!!)
