Hi!
Thank you so much for supporting us and purchasing our game!
First of all, we apologize for the late reply. Since you left your comment, we've been working on the mini-game guide (walkthroughs). The guide has now been uploaded to our Patreon and it's completely free for everyone to access. You can find the link in the game's description. (Though we assume you don’t need it anymore (:
As for the text box appearing empty, that's actually not a bug. If you notice, our characters open and close their mouths with every line of dialogue. Because of this, the game needs a brief moment for the character's mouth animation to finish before the next line appears. We chose to do it this way because it creates a more natural and immersive conversation.
Many games tend to leave character sprites with their mouths open while they continue talking, but we intentionally avoid that to provide a better visual experience. The brief pause is part of that animation process, not an error.
Secondly, we'd like to say how incredibly happy your thoughtful and detailed review made us. Reading your feedback meant a lot to us and brought us immense joy. We're so glad you enjoyed the game and even binge-played it! Seeing players connect with and enjoy our work is one of the most rewarding parts of developing these games.
As for your question about Charles's route, there are only two endings for his route, and you've already experienced both of them. Altogether, the game has seven endings across all routes.
We're truly grateful for your support, and we hope you continue to enjoy our future games!
Warm Regards
Team ZS Studios
