Nice game! The game could use a bit of polishing such as the pixel squares in the art, the Particle systems, and player movement. Some pixel squares looked bigger than the other and I didn't really get a good feel for the snow with the Particle Systems probably because the particles were parented in the camera maybe? And, the penguin also didn't flip to the other direction when moving left. Overall though, the gameplay was enjoyable and challenging, the music was pretty chill, and the concept was nice!
