Wow, this map must have been a crazy amount of work! I've never played an adventure map before, but I had a lot of fun getting through all the puzzles. I only got enough secret coins for, what appears to be the level 2? ending. The puzzles and stuff are great, but the mapping and layout was gorgeous!
Question, though, any reason the gamemode wasn't set to Adventure so you can't break blocks? I don't know much about adventure maps, so I'm curious.
