1939

It's got potential.

reminds me of that game that was just like this for NES. 1942 or sumtin it was called. good game. if u make a second wwII flying game then u should make multiple types of planes that shoot differently and possibly dont fly in a sraight line at all times.

Not very interesting. The background is basically a blue field (fly lower, put more islands) the explosion graphics don't mesh with the general retro shooter style, and you need an auto-shoot, for starters. In your place I'd withdraw this game and work on it some more before re-releasing it. Since the game has a bit of a 'war in the Pacific' feel to it right now, I'd rename it so it's not a blatant anachronism, but that's really minor, although it would probably help with creativity if you chose a theme firmly and did a bit of historical research. Just saying.

It looks a lot like the Game Maker shoot em up tutorial, except not done.
