Great game, would play again. I did end up having to look up a guide but that's on me wanting to unlock everything. I never did run into the ghost no matter how many times I played though

The gnawing teeth at the front door...the dolls lurking the hall...the ghost whispering beside your bed....these are all scary, sure, but this game makes you confront a terror FAR greater than any monster... Efficient time management!!! Juggle dealing with 5 monsters, each with their own mechanics, and survive till 5am. Everything you do takes time and/or power to do, the challenge is in figuring out the attack patterns and how to time them to your advantage. The more you encounter the creatures, the more exp you get, you can use this in your journal to unlock hints. You get all the achievements by completing the journal entries, and clearing the game. (By the time I had enough to unlock all the hints tho, I had mostly figured the patterns out.) Finally figured out a winning schedule in a little over an hour, it's def possible to clear in less time. I honestly can't think of a single complaint. This was pretty great! The creatures are cool, everything makes sense, and I had a lot of fun trying to map out a survival plan. A good spooky freebie you'll be glad to have in your library!

There's no clear directions on how to defend against enemies, freezing the camera when things happen traps the player in a death loop, and gets boring quick. No end in sight, just a headache. The worst kind of confusion that just stops progression. 0/10

This has a really interesting idea and its been implemented well. It reminds me of the OG FNAF games where you slowly learn how to get around each creature. The creatures are also quite creepy in their own right.

Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

The Toxic Commando Game Pass add landed on 12 November. Our price record since late September shows the key route barely moved, which changes what a subscription is worth.

Games like Titanfall 2, for the pilot or for the Titan

Titanfall 2's campaign changed its own rules every mission. Games like Titanfall 2 that keep one part of it — the wall-running, the mech, or a campaign that never settles.

It Takes Two cannot be played alone, and that is the whole design. Games like It Takes Two that give each player a different job — including one that makes do with a single pair of hands.
