I've played this game way back in the day and I still love to come back to it every now and than. I always end up playing for longer than intended and beating the game within a few hours LOL!
Honestly, the game is good enough to warrant a Steam or GOG release (with the same achievements as on Newgrounds and for an affordable price of between 5 and 7 Euros). Would you be willing to do that, SilenGames? I'd buy that pretty much in an instant!
