@carry the interesting bit is the Frost Walker style placement, not just the move itself. If the water needs air above it and the cube has to start on ground, that stops a lot of silly exploits but still leaves room for some proper path builds. That is the kind of constraint I actually like in snapshots – strong enough to feel different, narrow enough that it wont replace every other ice block in the game. The new ambient sound for Ice Crystals is a small touch, but it makes the whole colder set feel more alive.
