Having a snowman holding a candle to see in the dark is such a good idea. I like how the ice blocks are hidden in the darkness and restricting the amount of candlelight is an awesome mechanic. The invisible platforms are arranged in a really good way and I like how collecting ice cream cones can extend your ability to see the platforms. I like the warm glow effect from the candle and then lighting the candle at the end of the level is a really nice touch. The only thing I can see that could be improved is the moon which is in front of the ice blocks on the maze level which could be moved back a layer
I'll keep you posted when I make my YouTube video, which all being well should be tomorrow
