[MINOR SPOILERS]
I like the idea behind this game! It took me a few tries to figure out the killer, and while I liked the first "twist" from picking a suspicious person and having them be something that wasn't the murderer, I was not as impressed by it when it happened a second time. I was also a little annoyed with the way the game is setup; after the first 2 tries, I had already heard all the dialogue and didn't really have any other suspicious people I wanted to guess, so I sort of just sat around waiting the two minutes so I could accuse again. I ended up picking the correct person, but I didn't feel super accomplished at the end because they didn't seem all that suspicious in the first place and I was just guessing until I got it right. I think it would be really cool to make the rewind go backwards in time so you could get different dialogue or watch as people left/came back, but I understand this was only a week-long jam. ;) Anyway, I may have just had a not-so-great experience with the game, but I did enjoy playing; also, the graphics were really amazing! Overall, great job on this game, and I think you could definitely expand it!
