The Exit 8 (with bonus movie review!)
There's something to be said about games you can learn and finish in under 2 hours.
Clicking the game from your store of choice loads you straight into to game, you can pause to change settings etc, but you're immediately immersed.
No 5 hour 'tutorial' (cough BOTW cough cough TOTK), no playing for hours before the intro title rolls the screen, just very simple instructions seamlessly woven into the game's setting and off you go.
I'll leave out specific details because I think it's good to go in pretty blind, but essentially it's a puzzle walking simulator where you play spot the difference. Some are obvious, some are subtle, and you get better at spotting them as you play.
There's some very mild frights but mostly just a loop of either spotting the difference and feeling proud, or getting back to 0 and being frustrated at missing something!
If you're interested, have a look at a store page for it, I think the screenshots and videos will give you enough info to decide if you like it and want to jump in.
There's also a movie, I played the game and watched the movie in the same day, I really enjoyed both! It's not often I like movie adaptations of games but this one is great, it really sells the vibe of the game.
9/10 for both!
