Strange, I think you're the first person to report that kind of glitching. If it's not too much trouble, would you be willing to share some of your specs and browser used to see if we can try to pinpoint on our end where the issue comes from? The only thing that really happens when the ice comes out is that a mask/shader comes on screen to modify the length of the pillar.
Thanks for trying out the game though, it's a bummer that you couldn't get the actual working graphics of the game :-(
