This is a pretty good first game! I was a bit confused at first since I thought that it would be a bit more logic based (unless I missed something), but it seems that you just have to find the odd one out. If you continue to work on this game, I would suggest trying to expand the logic so you have to deduct who’s lying rather than just seeing who’s different (I’d suggest https://www.zeldadungeon.net/wiki/Anouki_Estates as a resource). I also just remembered that the parlor puzzle in Blue Prince has a similar setup (although your game makes it a bit more difficult with the timed aspect)
Very strong entry!
