Loved this, wow. Fez and Super Metroid's funky weird kid who's in their animal obsession phase.
Absolutely gorgeous game. I looked at the filesize and how is it only 80-something megabytes? The colours, the lighting, the effects. Genuinely one of the prettiest games I've played.
Design-wise, loved the lack of handholding, loved the multiple intuitive uses for each item (some interactions really caught me off guard), loved the movement and lack of combat. Level design is superb, so densely packed with secrets and puzzles. And one sequence to get the P. Flame was one of the best "wow, this game has made me feel like a genius" moments I've ever had in a game.
Like Fez, this game's layers of esoteric puzzles that require community collaboration and secret codes and interpretations and digging have completely washed over me. I just don't care and I'm okay with that. I didn't use a walkthrough or seek any help until I reached the credits and I was happy with that. But then I did search the cat codes after that point because I really fucking wanted to free them and frankly didn't feel like combing through this massive map in the hopes of finding more of them.
