I really liked this, the concept is incredibly unique. Never seen anything like this before. The moving towers can actually help you too, if you didn't put enough towers at the bottom! So it's more than just an annoyance, it actually can alter the way you play. Instead of just chasing down the runaways, you can move the runaways wherever you need them on the map. Really clever idea :)
With just a bit more polish, this could easily be sold! It's a unique idea. I kinda wish that there were hotkeys, but that's just because I wanted to be a pro gamer at this :)
Good work guys!
