My favorite regular level (counting the Map Piece levels) is the BuiBui Fort 3. It is mostly a timing challenge level with lots of spikes to avoid and sudden death, which before all the obstacles are avoided and all the BuiBui units are defeated, you can only have 2-3 LocoRocos, and usually just 1 spike/bomb hit results to cause all 2-3 LocoRocos to get stung are so it will result in death. I really like challenging myself.
That would be my least favorite level (never have finished it). I'm not a fan of the water levels either.
I like the levels with fireworks.

Yeah! I absolutely love Challenging myself and Bui Bui Fort 3 was one of my favorites next to Kelapton 2 and Jao Jab 3. (sigh) nobody appreciates a challenge. At least I found someone who does.
