Hey dev,

I wanna make a small suggestion regarding new players. A lot of new players don't know the basic positions on the map and build on wrong places and it is very frustrating. You can paint with tiles "X' on the positions (just like you painted "Green TD") so they learn where they should stay.

If you cant understand me, look at this image so you can get what i'm talking about:
