Very fun game!
Two minor inconveniences though, sometimes the controls were a bit sticky (as the others have said), but this only happened a couple times and I think on just one particular level so not THAT bad tbh. The other thing is that it is a bit of a shame that the viruses/bacteria seem to already start multiplying before you click start, giving you no time to read the text. If you fix those two things I'll give this 5*s ;)
