my cursor was still visible over the in game one (google chrome, windows vista if that makes any difference) but i actually kind of liked how the smaller one would trail behind it, so w/e.
I liked the game a lot, but given the time you've put in to create the animations and characters, maybe you should consider re using them for a sequel that has a higher jump, a little faster move speed, and allow the dog to attack soldiers by jumping at their heads, just like at the end, but maybe change to the animation from the guy getting hit by a mortar.
that could make for a really cool sequel. Keep up the good work
