I tried it. Some screens are gorgeous, some are worse - but it depends on tileset.
I remember there's similar level by Saba. I tried to make something like this several years ago but I abandoned it, so the idea is not unique. But I liked it and I thing it might be useful to see some less frequent tilesets in use.
Really? I'd love to see that level by Saba! *goes [search]ing*
But thank you! I do try to do what I can with the less interesting tilesets, but sometimes, there's not much I -can- do.
EDIT: Okay, I'm gonna need a bit of help from someone. I'm doing tileset 183, which is "RFC1459 Conversion" from #mas2. For all of the conversion tilesets, I've actually taken screens out from the game they're from as that screen (with the exception of Music Madness because #mas' screen is too tall >.> ) I found the actual secret in #mas2, but I can't get to it. I apparently need to flip gravity or something. So, in short, could someone send me a message with a map of Souleye's level in #mas2? Pwease? :3
EDIT2: Got it now, thanks to Gorfinhofin's LP of MOS on YouTube.
