Snake Pass' bright colors and quirky characters Doodle and Noodle easily hide its true nature - this game is hard.
It's a very particular kind of difficult game as well, something you won't get a sense of until maybe the third or fourth level. Snake Pass isn't just asking you to play as a snake. In essence, it's asking you to think like one. When you move Noodle, you can't ask him to go in a straight line, holding forward on the control stick - that's not how snakes move! Instead, you'll find yourself moving left and right, allowing your snake to slither about at a pace respectable for serpents.
You'll be doing this to collect all the collectibles, in a fashion found amongst most puzzle-platformers. But if you don't gel well with the game's unique physics engine, you're going to find it difficult to get everything. But that's also part of the game's charm. There's nothing quite like figuring out the right way to coil around a few poles, gripping tight, and letting Doodle give you a final push by lifting your tail up before grabbing the game's more difficult to reach coins. And checkpoints are near-instantaneous, meaning if you fail - and you will, a lot - then it won't take long to get back on your slippery way.
I mentioned this game looks bright - that's a bit of an understatement. It really pops with its colors and atmosphere. Doodle and Noodle are adorable, and I think Sumo Digital agree, seeing as they let the four face buttons of your controller change Noodle's quirky facial expressions. This is further exemplified by David Wise's amazing-as-usual soundtrack. The man's still got it. The addictive songs make it a bit more bearable when you're spending an extra amount of time on a particular level to find that last hidden collectible.
Overall I'm happy with Snake Pass. It's a perfect pallet cleanser after a massive undertaking like Breath of the Wild. And though the unique controls take a bit to get used to, with some persistence, you'll be slithering along with the best of them.
