This is a certified banger.
It starts a bit slow, but when it picks up, it really hooks you in. I Really enjoyed the distinct personalities of each character and how they clash with each other.
The MC gave off an annoying impression at first (which i believe is intentional as he's a professor) but quickly grew on me when he started engaging in banter with "Massimo". Their dynamic is great.
The game is highly polished, the VN backgrounds are really atmospheric and the in-game locations set the scene perfectly. The soundtrack bops and is appropriate to the scenes. There may have been a few minor bugs, but nothing gamebreaking.
Overally the vibe is great, the mystery intriguing and the gameplay engaging. I had tons of fun and i'm looking forward to playing the finished game!
Good job team, and good luck!
