hi BK
 
	 
 
	Can you do it in the form of waves, coming from 4 sides. it becomes a more difficult mode. But is it possible? 
 
	 
 
	Do you slow down the game because there will be a lot of intense attacks? is there any traffic? of course, it will be very difficult to defend the last wave
 
	 
 
	it would also be a more enjoyable defense if there were 2 possibilities for each player from the destroyer and terminator.
 
	 
 
	what do you think is possible?
