Okay, Weapon upgrades, despite seeming like a downgrade in reality you shoot faster and your attacks do more damage, but seeing as most of the time one or two bullets will kill anything you might not notice. The curser may look alot like an enemy but it's alot easier to see where you shots are heading then try and pinpoint where on earth your curser is. All in all a good game, of course there are things that could be improved, but isn't that why there was a sequel made?
Hah :P
