I actually never had any intention on making a 5th quest entry myself. I love the idea, and probably would've had I not ruined my last system.
There is a chance that by November I'll have a new system and participate in the judging process though, so best of luck to all the entrants. At that time, though, I'll probably finish up the hookshot code and pegasus boots, and make some soldiers with line of site, etc.. to finish up the LttP functionality.
Please don't make them too hard! I spent almost an hour running around 3rd quest and still never even found level 1!
