Alright thanks for your input

I've made the first few attack waves quite a bit weaker. It helps, but its still not an easy map.
I also would like to inform you that the map in its current state is

UNBEATEN

As far as I know, no team has made it to the end yet. A few came close, but not all the way
I invite you all to get a team together and beat it, cause I can't test the last levels without anyone actually getting there

Modify the map so that you start with tons of extra units and defenses.
