Yes, I did this. I need some accomplishment in my life.
A - Left D - Right E - Shoot some ice. You may need to just spam E to get something to happen. You also have to get away from the edge to shoot. Yeah, that's right, I'm lazy. Mouse pointer - Move your mouse to aim the ice. Tip: If you hold down E and then press A or D then your ice stuff will turn into a bunch of stickmen. This literally took me twenty minutes...
