Sweet short little game. I liked the art and the music.
Btw as you said in the description that the game was being detected as a virus in some PCs. For that I have too experienced that problem earlier. I think it is related to the digital signatures of the exe file. And I dunno the case about other engines, but with Unity if we try to change the icon of our game then this problem occurs. As if adding our own icon removes the default digital signature or something from the exe file. So the solution that works for Unity is to not change the icon of the game.
I think you made it in some other engine, so not sure if this solution would work or not. But yeah these false warnings from antiviruses are sure not a pleasant thing for us game developers :)
