Obviously very barebones, but still kinda interesting. I think there is something to a horror fishing game, I guess Dredge did do well for a reason. I'm not sure if a hunger/timer mechanic works with it too well since fishing games nearly always involve a very heavy luck factor. But there could be something there, maybe not a risk of a timer but some other sort of risk that you have to look out for. I don't really know though to be honest
It's pretty impossible to invent new fishing minigames at this point, but I don't think I've actually seen an on rails rhythm minigame thing mixed in before. Could defs be interesting.
