Not a bad game but still needs a lot to be fixed. There are no screamers, and the mechanics of the haunting, chasing and hiding are quite strange to understand sometimes. What is more, the game is a bit repetetive - you only need to examine the objects to find the cursed ones, and then bring them to the basement in short time. It's great that there are different characters with different skills, but there's only one useful character - a priest (or whoever he is, that religious guy with the cross). All the rest are just for fun, no more.
I have spent some time on this game, and id like to address some of the common things said in reviews that may have you, yes, you, looking at those reviews trying to determine whether or not that 10 bucks is worth it, and if your like me, your a bit beside yourself. first thing, this game i would really consider to be inspired by phasmophobia if anything, its a completely different concept, and completely different items. you will probably like it if you like Phas, but i wouldn't walk into this expecting to be met with a familiar challenge. second, i see nothing that screams abandoned, sure there are some bugs, but its an early access game and they are far from game breaking. My worst one was when i unlocked an item, i bought it and it didn't show up, i had to leave and come back to get it to purchase properly, but it works just fine after that. a good note is that the game is scary. there's nothing psychological about it, i nearly shat up my back several time playing it. Now, im a horror game lover, but im not super scared of them normally, im good with jumpscares and stuff and i walk into it all eyes open. So for me to say i genuinely closed my eyes and turned away from my computer because i was scared, really puts this game at the top of a list for me. i love cupcake, and you'll love him too. another thing i recall reading in the reviews was someone said only one character can hide, this simply just isn't true. there are many places to hide in each map, they just aren't as obvious as normal hiding spots. hiding behind a washer or desk works just fine. Luther has a crucifix as his ability, this lets him survive in the open, which isn't even hiding, its just a perk, everyone can hide. i played it with 2 of my friends, all of us just about peed ourselves and we did lose quite a bit, I'm not sure id recommend playing alone, but that's just me. Hopefully this clears up anything in the other reviews that may be stopping you from giving this game a go! i highly recommend giving it a shot, I've had so much fun so far!! amazing game, cant wait to see more from it!
Unexpectedly great game. I have bought a bunch of these style of games and they are good for a laugh or two but this one I have played for hours at a time now. The endless mode is my favorite as it becomes more and more chaotic the higher your team progresses. Devs seem pretty responsive if you reach out on discord and patch things quickly.
