Im so glad I had a controller handy to play this! I love the movement the most: Climbing is simple and responsive with the controller vibration, and its super fun to slingshot yourself upwards on the bigger gaps! It feels like a more fluid and speedy Human Fall Flat if you've ever played that game.
I also like the 3d screen/fisheye lens and the charming variety of stars and planets etc. in the art :)
My only critisism would be that requiring controller is a bit limiting for who can play the game (i totally get why a game like this works much better on controller though).
