Perhaps I'm not very qualified to review this game since I did not have someone else to play it with, so with that said here are my thoughts. I thought the movement was really inventive and was done really smoothly, I loved slithering around in general. I really enjoyed the aesthetics and the music, together it made the game feel like a Nintendo Wii kind of trippy game. I think the checkpoints were really forgiving, you could just pass it with one ball and the other ball would now spawn there too regardless of if they actually reached, I was able to beat the game solo with it. I like the progression of difficulty, simple switch puzzles to moving obstacles to obstacles that each player can control. Even in solo, this is a pretty tight game, but apologies I couldn't play the game in the intended way.
