Very awesome game so far! May I suggest a very expensive late game purchase that would reset all of progress but add phenomenal benefits to your game. Say a profit multiplier, maintenance fees decreased, or tick/second increase. Call it something like a "Promotion" maybe!
I think it would awesome to see the actual video of the attack from your attack log. That way you could see how you can improve your base. [+] so devs can see this
I tried clicking on the cavern after the 5th waves and now it is giving me the: "Oops. something broke" message. Any suggestions? I have a fast internet connection. I only opened the game in 1 spot. And my computer is super fast.
