A well designed level with a nice flow and almost no gameplay flaws (perhaps a spring at 78,68 would be a good idea?). The atmosphere is really nice, the music fits the level, although it could use more background eyecandy (yes yes I know, Rag said you don’t need to but it would still be great). One thing though: why the invisible walls on the left side? They can be quite confusing.
Other than that, it’s a good level! Make some more :P
