So a pretty basic concept, control two players simultaneously. That said, the artwork is very clean and looks wonderful. I also really like the music, it's a great fit.
The level progression is perfect, it introduces you on how to play nice and slowly and allows you to get your mind around the concept rather than dropping you in at the deep end. There's a good amount of levels to satisfy the gameplay too. My only criticism is that this level:
was randomly 10x harder for me for some reason. I did all the other levels either first try, or within 3-4 times. This one took me like 50 tries.
There is some missing polish here and there like others have mentioned the ground is very slippery, and also when you die / complete the level, your character can keep moving / fall to their death.
But other than that, what a wonderful submission. Best of luck!
