Hello Friend! you have a cool game, but the level with crabs (maybe they are not crabs, but I called them so) is very difficult, a lot of them are created.
And I was cool to play a game about viruses from a other of the developer, because I also created a game "virus hunter" and it was interesting to see other ideas
Hi! the general strategy is to kill the spiders first before they start spreading, but once they do it's really hard to make a come back.
Do you happen to know the number of night you are getting stuck at ? maybe I can balance it a little bit :)
(internally we call them spiders, but they do look like crabs as well)
