Since it is too short to make it difficult in a fair way (at least in my opinion), I came up with the idea to change things differently with this level.
If you played the original level in The Invasion 2, then you probably know about the catch of the exit being a death trap, like in somekind of SMW-hack.
But that is probably all you can use as knowledge about this level, as I changed things up from the original.
The shadow-version of the level features also another twist. :-)
