I like the idea... BUT!
clicking the arrows to select monsters and waves are a bit slow... also, when you reload to edit maps, there is an image of white square. (But the mobs load well in the Protector III.)
There NEEDS to be a way to remove paths that are placed. please consider using the righ click to remove the path. I tested one Test Map I made, but the inability to remove waypoint leads to a point where my mobs are stuck in a corner. (Imagine just putting a fighter there to kill them)
3/5 for now for those bugs and glitches and not full function...
