people who say this game is stupid or "same" as other is fucking stupid, ALL VIDEO GAMES from fantasy whatever balls to your math homework is JUST A FUCKING MATH SIMULATOR added on with some color dots to simulate your caveman eyes and primitive reptilian brain, so just click away you big sack of MUTATED SPERM CELL. I for one enjoyed this math game, I'd prefer more difficulty by adding more resource, X factor event like sperm death from temp change, disease etc.
