Highly recommend turbowarp The counters and some other features only work on turbowarp with unlimited clones, you've been warned though, the infected cells could duplicate and lag turbowarp pretty bad. Turbowarp: https://turbowarp.org/1363211358?clones=Infinity&hqpen&fps=60 The cells will try to run away from your mouse, so you could try to stop the infected cells or infect every healthy cell.
I might remake this where there's no clones later
