Real fun, but please, for the love of god put some sort of checkpoint on that snow golem fight, the dread of having to go back to the beginning after so much work is absolutely frustrating, and not in a good way.
Also medals and high scores aren't working properly, I'm fourth on the leaderboard in game, but I'm not on the Newgrounds leaderboard, nor do I have any of the medals. I see there is no easy mode, so I guess this is all because you're still working on it, and I eagerly await the next update. Edit: Everything is working now.
For anyone still stuck on the snow golem, he can't punch the area where his head is, so try to stay there, the area to the left of his torso is certain death if you stay there for more than half a second, if your there and just took a punch try going backwards and then flying over his head,
The best strategy is to stay ahead of him by repeatedly falling into the snow to cool down than rocketing up, rinse repeat.
