As others have pointed out, this game just completely turns on its head once you unlock Fatality. It becomes very slow and essentially revolves around getting different buyables across multiple tabs. That's a shame, as the game up to that is quite fun and engaging.

@unpogged you can hold shift to bulk attempt mutate. It's important but the game doesn't make it clear.

i really would like to play this tree, but it is unplayable on my small machine.
it's the only tree i can't play. profiling in chrome shows that updateTemp, updateTempData use 100% cpu even after hard reset with just one virus.
that isn't the case in other tree mods, so i assume there are big optimization problems in the code.

zero deaths and 'ZERO' deaths are achieved by going into fatality challenge 4 and disabling the multiplier boost autobuyer (combine casualty challenge 1 with fatality challenge 4 for 'ZERO' deaths)
