Looks very nice and polished, I didn't get to finish it though because I didn't realise I was supposed to fill in the timeline. I explored the whole house, found the clues, talked to the suspects but then I didn't know what I was supposed to do. I came to the comments section for ideas and saw about the timeline. Hopefully I will have time to have another go tomorrow because it looks like a very cute game and sadly I think there are some spoiler-y comments but I can't wait to see how it ends.
Also, it would be better if it didn't require a scrollwheel, not all of us have one! (Laptop, no mouse and the 2 finger gesture on the glidepad isn't easy to control)
And, I'm pretty sure Rex is actually a duck hah
