I bought this game without hesitation and I'm glad I did, it's really fun and more than worth the money. My only real issue is with labelling - sure, it's a love letter to N64 3D platformers, but the game itself is barely a platformer. The only real platformer level is Bright Forest and the final challenge (no spoilers lol), other levels have barely any platforming challenges or gimmicks - but ton of puzzles.
So instead, to me this game feels more like an adventure game that uses a "wrapper" of mechanics of a 3D platformer around the exploration and the puzzles. The fact that you can't even actually die or lose in any way ends up just reinforcing the adventure focus, but I seriously admire this as a bold decision to make. Of course that genre thing is not really a problem for me, because I love adventure games so I was positively surprised - I'm just saying.
Overall I really like this game, I followed the creator on itch, and I will def check out Kiwi 64 and Toree 3D. I'm curious if they will also play like that, or differently.
