100% completed the main game (gonna play new adventures and the museum now), this is seriously the best puzzle game I have ever played and one of the best games I have ever played period. The amount of outside the box thinking is unparalleled, some of the later puzzles really pushed me to my absolute limit. Crushers was the hardest puzzle in the game for me

EDIT: As of December 31st 2021, I finished New Adventures, I feel like it has a few puzzles I think aren't great, and the 3D mechanic is absolutely dreadful and made me genuinely nauseous (although don't worry it's only around for the babarcade world), it's still baba and baba is awesome as fuck

I haven't completed every puzzle in the game just yet, I have a bit over 30 left, but wow. This is one of the best puzzle games I've ever played, my second favourite behind the untoppable Baba is You for me. The way it balances introducing new mechanics and making use of old ones is incredible, 2022 isn't very far along yet but this is definitely a contender for GOTY for me. It's insane how far some mechanics are pushed, and then pushed even further still. My single complaint is that I felt there wasn't enough difficulty, but not everything needs to be Baba Is You, where I spent upwards of 3 hours completing some single levels. I beat the main game in about 15 hours, 100%ing every world as I went. But yeah, I played the demo before this launched and I had faith it would be genius, I'm glad I was right.

EDIT: I've 100%'d the game now, the post-game is incredibly cool and I love the slight jump in difficulty for the final world, this game is just so awesome.
