Gosquares, Thank You!
Finally, I found a game that actually let me play directly to the game. No registration, no loading time. As simple as installing and start playing. I don't care if it has no sounds since I'm playing it while playing my favorite YouTube channel anyway. Give Gosquares a try, it's a good game for killing time. Still would be better if I can play it offline.
