Just out of simple curiosity, would it be possible to add something like an elapsed time? It's probably too late to add a total elapsed time from the very start, but maybe an elapsed time since last reset? And maybe add 24 hours to that when someone buys the time warp? Also, how about a total cash per second?
Dang, knew I shouldn't have reset and cashed in on those angels. 1.3.0 slowed the oil company down to 8 seconds from 4 seconds in the previous version.
