Anytime I download the game it shows me that its an virus. Is it actually???

Nope,I have it installed.

I think it does that because its an exe file.

Not virus, just ignore the warnings.

It's not a virus propably this game haven't got a microsoft certification and system thinking it's can be a virus.

KAROSSSSSS Is Right! You can just ignore the warning

Windows is just scared of any foreign .exe files.

So no, it's not a virus.

i guess this game is viral

exe is a known file for trojan, buuuut that was long ago now it's just used to not have any extra files like data, images etc in really tiny games (like 20 mb in this case) plus many, and i mean MANY people have downloaded this and nothing happened, so you are 99.99% safe here.
