Myrtle STFU with that ethical stuff here, else we take evry single fking GAME(fictional, funny, commedy) , though it has not to be logic, i mean 4 decisions make the whole life? and there is one mistake in your argumentation the fact is you see a sperm having a males DNA getting into egg and female one wanna go in too which is impssible if you didnt slept in biology class, 2nd if a second get in we would get 2egg twins.... so yeah, the idea with the x quite neat BUT he calls the girl the plague.. same u would call if you switch the gender of the sperms an intruder no matter what he/she is if unwanted is a plague
very nice game, only fristrationg thing, dying with NOT touching, dying at corners, even if i you can ca see the space between block and edge O,O nethertheless nice concept ^^
did it in first try, the key is making obious one and then sort out connections and looking where you can place the combination and not the single ones ^^
