I've played through your whole pack, and wrote a review. Please don't be dissapointed because a 5.0 rating is not all that high, but if I'd give you a 9.8 it won't help you either, right?

The only thing you must consider is being different and having lots of details in your levels. Oh, and good luck. Should you need betatesters, contact me under pht2@gmx.de

EDIT: I don't want to say you're levels suck or something, they only lack "the special element". You're "mapping style" has also some good points, like your levels being pretty long. Keep on it, ok?
