Great art! I found it a little hard to actually hit all the enemies at once, because they flew out of the screen too often. (Maybe im just slow)
Just FYI on larger format monitors you cannot see the (Y) to apply changes on the options screen. So it took me about 5 min to get a size i could play on. Consider making it windowed by default! Continue shows up even though i've never played? D-Pad doesn't work.
