I figured out some parts of the spell system and used it to make a wide, long, short platform that floated in the air and didn't spin when I stepped on it. I then spent a good 2-3 minutes building a staircase to the top, but ran into a bubble and got knocked all the way back down.
It's a cool game with an interesting system! Might get back to it later when I'm willing to tackle those pesky bubbles.
