Still doesn't fit the theme, I mean I don't see a lot of changes TBH, It doesn't remind me of a blizzard, it reminds me of a snowy mountain and you're trying to find shelter on it. It is getting closer though.
It's really cool. But as stated above, the glowstone doesn't really look like stars, and the earth is pixel art. Also I think 5 checkpoints is too much for a normal parkour.
