Every once in a while there's a game that perfectly clicks with you. It's almost as if the developers had you in mind when they made it. For me, this game hit all the right buttons.
It may seem as a game with wonky controls (a la Octodad) and a sort of 3d platformer collect-a-thon , but it is much more than that. First, the controls are hard to master and that's why it may seem like they're bad, but once you learn them you realize they make a lot of sense and you're capable of doing everything you want.
Second, I'd describe this more as an experience similar to learning to ride a bike than just a video game genre. You start struggling "How am I supposed to do this?? I can't even stay on the bike/stick and I fall all the time!" then you start learning, slowly. You advance a little, manage to do something (albeit in a non optimal way). You feel proud of yourself. You keep pushing and eventually you get much better. You don't fall anymore. You have some problems with the turns, but you keep practicing. The game is very good at pushing you just a little every time. Doing every collectible, I felt like every level made me a bit better, punishing me until I was just starting to get frustrated. As time goes on you and Noodle (the snake) become one. Just like a bike, you stop thinking of every little move you have to make, you just flow.
The best part of the game for me were the collectibles. They don't serve any purpose other than challenging you though, but that's exactly why I liked them. They're very similar to Celeste's strawberries: a mini-challenge inside a level that rewards you for taking a harder path, doing a cool trick or just pushing yourself to be better.
Noodle is the other highlight. Just looking at her being so happy made me happy, and seeing her face of absolute panic as I'm nearly falling made me panic as well. Her coupled with the vibrant environments and amazing uplifting music just made me happy.
There's as much plot as a 2d Mario game, but it's fine. The game is not about telling a story, is this self-improvement journey. There's also some minor camera issues and some checkpoints that are way too far from the very dangerous thing I'm trying to do, but is all minor and it didn't hinder my enjoyment of the game.

I discoverd this game thanks to Game Maker's Toolkit Most Innovative 2017 game video, so give that a try if the game looked promising.
