wonderful game with wonderful graphics. but........ the bike ridding feels really weird. like your not on a bike at all. its mostly the turning and the motion. maybe get a better idea of bike ridding from how GTA does it.
also getting around the city can be a bit slow even with the bike. a lot of bugs and glitches but overall a really great job!
(Edit) also try not to use 7ZIP a lot of people don't know how to use it and its also outdated. Mega is the most common used and simple.
