This is my sixth pack! (Even though the first two were rubbish...) This time I just 
decided to go all out on the difficulty (You may still find it easy though).

If you find ANY backroutes or something please message me through any of the following
sites:
Lemmings Forum
Lemmings Heaven
Youtube

For solutions look at my youtube channel (gronkling).

Thank you for Akseli for backroute testing.
