@Cheetahmen, the 3rd screenshot shows in-game action. Another screenshot from elsewhere shows another game, but this is definitely a Contra pirate.
The label calls it "Snowfield Battle", which is an old flash version of Contra. But this game is totally unrelated; you're clearly fighting in the Jungle and (3rd shot) character sprites are simplified transparent drawings.
@RobGBA, I actually would want to buy it because I collect Contra stuff and this pirate is very interesting.
