There should be a level all heroes by this amount... Preferably level all heroes before the last hero bought by this amount. It'll save so much time...
I'd like to see skills become more useful, one thing that I hate is that when I activate a skill it deactivates my idle, rendering the dps boost useless along with the gold bonus, I would also like to see more skills that pertain to the style of each specific hero like Betty Clicker can get one that increases hero dps by 20% for 30 seconds. I'd like to see skills improve over time as well. You can add more skills by adding a scroll bar off to the side (+) for the developer to see.
Wait, I just built a laboratory in 2 days, then it was over run by zombies. I reclaimed it and it tells me that creepy experiments where going on in the laboratory, zombies chained on treadmills, zombies on an MRI, zombies with parts of their brains cut out, and all kinds of weird experiments. Who did that in the laboratory that I personally built yesterday?
