I won't get into It much nor spoil anything. I went into this blind not really knowing of the YouTube series. But I fell in love with this game and frankly the series on YouTube after falling into a rabbit hole of sorts.
Every character is so weird, different and just full of personality (or rather personality's considering the main protag). All of which makes them quite memorable. Even with the minimal gameplay (most of It being going from point A to point B if there is any, some platforming or collecting items) the real "meat" of It is either observing or interacting with the characters and world where rules and logic are more of a suggestion.
I'm not really sure If there are underlying metaphors or an overarching story in this since the creator (Joel G) said that the YouTube series, which I'm not sure If It's even connected with the game, was mostly just nonsense. But in a odd way It makes no sense to the point It does somehow. It's weirdly relatable in a way I can't describe.
I couldn't recommend It more considering the first episode is free on Steam. Plus there being a supporters pack that you can buy where you get the OST of the game. I really look forward to seeing more of this, including the short animations on YouTube. I had too much fun writing this lol.
I played part of it, but my controller was freaking out so I stopped at a difficult platforming area. It was fun, and I did go and watch the youtube series afterwards.
