Thanks for the tip! I don't notice any significant difference when improving the crit damage though.
i can see that youre spending the third (last) currency on upgrades instead of merging into tier 3 unit, always get a tier 3 unit and upgrade it as much as possible,
i dont have any problems winning with radiation / explosion / ray but thats probably because i know what to do, youre really close from getting into the part where you say "thats all they can do?" :D because tier 3 units get really OP really fast when done correctly
Thanks, I've tried several different strategies, including getting a tier 3 unit before investing in upgrades, but I still don't see a significant difference. I'm not sure what else can explain the difference in our experiences other than the behaviour being affected by the OS or browser or something specific.
