It's decent...
Junglefeet beat me to the point. But still, you mixed up the numbers, the battle over the pacific in WWII happened in 1943, not 1493. Also, not to mention, airplanes didn't exist in the 15th century, so that's ridiculous in itself
Go to http://www.newgrounds.com/account/fla sh/edit/567770 to fix that.
Aside from the messed up title, the game was decent, and I'll give a 7 for the effort.
Nice job
