Don't worry about me. You can have the contest go on for longer if you want, heck, you can even extend the level submission phase and nag people to make submissions to have a few more levels in the pool (Clam, Steve, Pieuw, namida, ..., and of course yourself, mobius!). I'm not even sure whether I'll have enough time tomorrow to give the new versions of the existing levels a good shot.
As for determining whether a solution to my level is intended or not - for simplicity, if you don't have the time to look at the actual solutions, you could just consider any solution to version 2 of my level intended. Either way, I got a level submitted to the contest, that's all that counts for me.
