I honestly loved this, seeing as I'm the kind of person that loves games where I can explore different aspects of a person's life and try to figure out a mystery.
The battery mechanic was really good at adding time pressure, though of course my first instinct was to go and play with the tamagotchi despite it. You can imagine my surprise when that ended up actually being useful!
I did end up running out of battery, but got the suspect right anyways! There's a lot of good leads that were fun to pick up on, but honestly would've loved it if it was just a tad longer/more complex with more variables to consider. As it is though, I really enjoyed it ^^
Great job!
