This is a really cool game! I appreciate that it was especially forgiving when it came to restarting or checking other routes too. It's a smart feature to offer to rollback from the screen, and save some time based on how I think most players are playing a visual novel with high stakes like this (reloading saves and checking what's on the other side of big choices).
At the start of the game I found the tense or point of view of the words switching between the first person "I", third person "He", and the player's name, a bit confusing to follow in the prologue section. Hopefully this isn't too off-putting to other players checking this out though, because after that the mystery story, sprite art, almost point and click type of exploration, and overall sound/voice acting was all solid and really crafted a sense of immersion I didn't expect from just peeking at the screenshots!
Overall, great work, and I hope to see more games from the members of this team in the future as well.
