Ice Block Cavern
It's a cavern... with ice blocks!
(Also, there's an outside area too... with more ice blocks!)
It shouldn't be too difficult to get through this level within 500 SMW seconds, but I set the timer to start at 700, just to give the player a good amount of leeway for puzzle-solving and optional stuff.
Now, I don't know why AddmusicK 1.04 gets stopped by AVIRA, but 1.03 worked for me, fortunately! (Thanks, MarkD, for suggesting I try that!)
CAUTION: I've had ZSNES occasionally crash on me while I was hitting multi-coin blocks in my level, most often when I did the block factory glitch on them, so be careful of that if you use ZSNES.
If anyone finds any true game-breaking issues with my level before the deadline, let me know.
