So I let the game run all day and I came back to a 460+ million combo...I figured I'd stop and upgrade the turtle spawn rate to about 3000 for each tube (took about 15 mins of continuous clicking) and noticed the turtles didn't come out any faster...
Right when I got to the point where I have the best location, completely filled with racks/booths, and full upgrades to everything I started freezing. After a minute or two it says the adobe flash plugin crashed so I reload and it freezes again. Any ideas on how to fix this? Anyone else having this problem?
