Thank you for playing and for your thoughtful feedback! You actually caught onto something interesting about the snow effects - we initially had a much larger GPU particle scene with quad mesh and snowflake materials that looked amazing. However, since we wanted the game to run smoothly in HTML5/web, we had to optimize heavily. We ended up using CPU particles for the snowfall while keeping GPU particles for the ski trails (both without shadows) to achieve that 2D aesthetic you noticed.
