Super cool idea - awesome pitch too, throwback to childhood imagination! I definitely enjoyed theory crafting some builds up, could see it develop more! One thing I struggled with was if i wanted to move with a character who could move far, i couldnt pan the screen without deselecting them, so occasionally I couldn't move them all the way down and to the right if i wanted to :P
Otherwise, i really enjoyed it, and the music was really cool too!
