There was a fair bit of stuff to shuffle through what I was playing and I swear I only figured out some of it later on. That said, I had leading them around in endless circles while I tried to level up as best I could. I could not tell when everything went kaboom (and my hp recharged) if I had won... or lost; it was kinda weird. Looking at it later, I realized your game quickly replays backwards as a way of showing you how you did.
Notes:
- You do not have it setup where the units closer to the bottom of the screen are set above the ones closer to the top, creating this weird feeling of enemies hover over the player, like they are trying to eat them.
