I thought I'd go ahead and share my level with the community for feedback before final judging. Thanks a bunch!
Volcanic Boiler V1.o1
I actually liked this one a lot. Good tileset mixing without going overboard (loved seeing those plants everywhere), exploration that actually rewards the player, and good sprite usage (finally a level that isn't a jerk with the darned volcano lotus plants!).
The only issue I could find was the time limit could use some extension, as I found myself running low on time not long after I found your easter egg, and considering the amount of stuff you've hidden, it'd be welcome. I also noticed a few cutoff pipes here and there, but I don't think there's anything that could really be done about that (and that stuff has already been discussed extensively in the VLDC discussion thread, I'm not going into it here)
