This is visually cute. I love that the penguin flies by spinning. In several areas, particularly the red zone, it was very difficult to see the terrain because everything was the same color. I wandered around the red zone for quite a while trying to figure out what to do before I realized there was an invisible ramp in the corner that I could walk up. I managed to fall off the world in the second zone and had to restart to recover. It happened because I tried to jump off one of the upper ledges and somehow got wedged between two pieces of terrain in area below.
