I wasn't sure how well I would pull this project off, but surprisingly it's going fairly well. My only problem I have left is Course 3, 4, 12 and 14, which is driving me nuts. I've tried different approaches, and just when I think I got it, something snags up!
Here's the problem:
Course 3: Believe it or not, the water is my enemy here. Trying to control Mario long enough while drawing the underwater areas is somewhat tricky to do. Atleast I got the secret cavern out of the way though.
Course 4 and 12 (since they are both mountain areas): I'm trying to do a top down tactic (start from the top and spiral downwards to the bottom), but all the hidden areas under certain parts of the mountains are causing me problems.
Course 14, I'm trying to do a bottom up tactic, but that's kinda getting tricky. Not sure why because I was able to do it in Course 7 pretty good. I might have an idea on what to do with this, but I still need to test it.
