As a fan of visual novels in this style, I had a good time playing this! The character portraits look super good.
As a side note: when confronting Dennis, if you present the correct item first, then the wrong item second, the game lets you retry, but instead of resuming right before presenting the second item, it expects me to present the first one again, to then attempt presenting the correct second evidence. It's a minor thing, but was a bit cumbersome to have to do the first step again. Regardless, good job on the game! Would love to play an expanded version :)
