Fun little mini-game. Felt a bit like Rampage or something like that. Would have liked to see a little more happening - moving boats, airplanes, stuff that runs away or fights back.
The weapon variety was fun, but I wish I had actually stuck with a given weapon longer. They all felt pretty much the same in the end.
The music was solid, but would have liked a lil more in the way of juicy sound effects for all these explosions.
