Creature Camp Conundrum

This is a puzzle game in a peculiar zoo setting where the player needs to find the culprit behind a serial disappearance case. To do so, each round, the player uncovers hints which will help to find the culprit by logical deduction. To make things more intersting, each round a new random creature disappears, potentially overthrowing the work done up to this point, but greatly (exponentially) decreasing the difficulty of the game. Goal is to find the culprit as fast as possible before too many creatures disappear.
