Sulphur Nimbus: Hel's Elixir Playthrough - 5 - Frozen Caves

Ice physics are actually kind of fun in this game. This is the only ice level, though. The idea of a hailstorm being an obstacle with overhangs to protect you is a very interesting and a nicely atmospheric idea too. Also, you can't fly straight up because gravity and inertia are a thing.
The boss here is actually pretty easy. It's basically Gunlegs, but there's three of them and no shield that knocks you back so you can pretty easily cheese them on normal mode. I tried to make the fight more interesting. Key word: tried.
