Thank you! We are happy that you liked it! The balancing is indeed out of shape, sadly we spent too much time trying to get my PC to run 6000 zombies at 60fps (this code is a mess, oh my) and we slept... That was a mistake...
Anyways, we plan to give it a proper balancing run now, with a tiny hope for a proper remake/cleanup, so you can check back in a while ;)
Alternatively I've been persuaded that we should have a discord, so here it is: https://discord.gg/ma6UsQu
Additionally I will try to find some colourblindness filters, we have a lot of colors that have meaning and also ones that don't, so I can see why this could be a serious problem!
