To those playing: if you want to be able to find your code again later, go to the CodeCombat home page and sign up for a free account! Sorry, we derped out and didn't put any signup form accessible from the Gridmancer level.

Also, we're sorry that we left you without good debugging tools: https://news.ycombinator.com/item?id=6976883 -- this is the #1 problem uncovered today. We will retreat in tearful shame to our code lairs until we can blow your minds with our timeless debugger.

You are amazing players--so many good solutions here. Thanks for playing! To those who sent in solutions and are looking for dev opportunities, we'll be in touch this weekend to see what we can do and learn about what you're looking for.
