thank you everybody! I am very glad that you liked this level

@Liwet, yes it is. I have provided many ways to make playing more interesting :)

Really nice map as usual. Thank you.

It's possible to circumvent the Customs House with tunnels. I'm not sure if this is intended or not.

what a crazy level - very tough. lots of fun though! very good challenge
