Okay, I finally got past that. Yikes...
So... I've actually beaten the level now, and I have to say: it's awesome! Razzorman, I like how you used all those familiar tilesets, and they're all among those that I really like, so I didn't mind that they're familiar. I loved the area where you mixed Smashy's All Purpose Tileset and The Almighty Zen Taco's Quiescent Archipelago (or whatever that was called), in particular. That, and the caves. But really, the whole level felt like you spent serious time/attention on making the screens look good and not too 'same-y'. Love the music, too - reminds me that I need to do a lot of music scouting yet for my big level...
Seriously, very nice work. IMO.
