The Square Root of -1EylandingIn DevelopmentThe square root of -1
# The square root of -1: Eylanding's new custom theory about the square root of negative numbers. A theory about complex numbers, balancing increasing real and imaginary rho, to manage multiple currencies. Make sure to think before you buy, because sometimes you'll really wish that a variable was one level lower. (You can lower variables in the perma upgrade tab dw) Link: <https://raw.githubusercontent.com/Eylanding/Exponential-idle/main/sqrt_of_minus_one.js> This theory currently take about 2.5 days to reach 1e240 (as far as I've made) using full autobuy and a pub multi of 5. Don't expect amazing balancing, that'll come later. Good luck!
