Cool little detective game. I thought the 'line of sight' feature was pretty cool, albiet sometimes responsible for some jarring moments where you think you are going to walk through an empty space then suddenly faceplant a wall. The music was a bit sore on the ears after a while, but I don't think it's bad - just needs a little variety here and there.
I thought the story was engaging, though I found the conslusion of the investigation quite confusing - maybe I missed something. The final act was really cool - I wasn't expecting the action-packed finale and I thought it was a great twist.
I also thought the LATTEr pun was funny, even though it was objectively dreadful (which all the best puns are)
Overall, nice work :)
