In the later levels on the hardest difficulty, it can take many tries to get a working setup that can actually complete the level’s first few waves, and many more for a completed or perfect run through. Each attempt requires placing down your defenders again and again, and then boosting them up, which can take several minutes with up to 30 defenders even for the initial placement before the 1st wave comes. It would be nice to be able save the initial positions of your defenders and load them up again after restarting a level, rather than having to manually replace them each time.
Save Defender Placement
It’s a good idea, often requested, but sadly it will have to wait for the sequel.
