I'm not sure how to get Nuru and Boris to the pillar with the hole BELOW the giant ice rink, but I am so annoyed with the ice I am skipping it. I feel like I probably missed a bunch of the ice temple but I'm not sure?
There was only an optional boss to fight in the ice temple. In any case, the fight system is kind of broken since I didn't spent too much time on it. This game was a birthday present for a dear friend, and I only released it because to have it somewhere, I'm glad people can enjoy it a bit even then. :)
