I just wanted to add I beat this map. I absolutely loved this level. I love any level dealing with arrays. It wasnt even close to as hard as I thought it was going to be. I made a quick and easy solution to understand how addRect worked. In the end I actually beat it with out having to make the more complex solution I anticipated on making.
When the hints are finally made can you maybe tell the users what brackets equals the rows and columns. I had the two backwards and it threw me off big time until I figured out my rows and columns were actually going a different way.
