Works really well on gamepad, which I appreciated right away. Movement feels smooth, and between the sprintand the satisfying little jump sound, just running around is fun. The particle effect while moving is a nice touch too.
The whole 3D spot-the-difference angle is clever. And the world does a good job of feeling very dreamlike, with the color palette complementing it. The music ties it together nicely and keeps it relaxed while searching. This was a pleasant world to be in and was really charming.
