The problem of it is it lacks any story or originality. Have you ever noticed how Single Player levels get much more fun if they have some story parts in it, or something not seen in every level? What's originality you may ask. Play FSP: Rent Collection then. Or Tomb Rabbit. Or TDI / TDI 2 (unfinished) from Moonblaze. Story? Play Another Story from Stripe. Then decide what's wrong about your pack. Good luck.
