Steamlining some of the gui elements. A continous waves without having to click would be great. Best flash game out there :)
You should start looking into Unity. Its easier and more powerful than flash
1 Pick Virus
2 Start in Canada, Greenland, New Zealand, Cuba (if not, restart)
3 Sell starting symptoms (if any), other than sneezing. If you don’t have sneezing, buy it
4 Buy 1-1-1-0 Resistances
5 Once your disease spreads to a few countries, sell sneezing to get rid of visibility
6 Wait until all countries are infected. If Madagascar closes or this is after day 30, restart
7 Pump 4 Drug Resistance and buy sneezing, coughing, vomiting
8 After a few days, unlock tier 2-3 keeping whatever symptoms it gives you
9 Buy fever, fatigue, diarrhea, pulmonary edema, hypersensitivity, hemorrhaging
10 Wait until everyone dies
IT WORKS!!!!!!
(comments: feel free to use liverfailure, dont go to tier 4
You need to try this like 20 times before it actually works. 95% luck 5% strategy)
