This was a great mystery game! It feels incredibly polished and complete, which is impressive given that it’s also ~2hrs long!
The UI is so well-designed, and the level of polish really sets it apart from vanilla renpy UI. The “now playing” music tab was a great touch for accessibility - it would be awesome if that was something you could toggle on/off in the options menu.
The story was really interesting, and the Clues tab was a great option to help track evidence and build theories. I didn’t figure everything out, but the majority of the reveal felt like something the player could have pieced together, which is nice. I agree with a couple other comments that the pacing and tone of the very end feels a little strange - [POSSIBLE SPOILERS AHEAD] I think you could get away without the last scene back in the house, and keep the fates of those characters a bit more mysterious.
Overall, a great entry with a clever mystery! Very nicely done.
