This is the type of a game I’m absolutely awful at, but I tried my best 😆
I think a few extra mechanics are needed, the core idea is sound, but for instance the first time I just stumbled upon the killer by accident and patted myself on the back instantly. Then it turned out it’s not that simple, however often it’s due to not having enough time to figure out where the killer might be on the map in given time.
I was thinking this lends itself actually to some extra mechanics, like skills or powerups that let you dash once in a while quicker across the map, stop time for a moment, peek across the map etc. etc., generally stuff that adds in a planning/agility element to it, and evens out the odds.
