Got 100% completion quite easily, no clue what everyone is complaining about. The medals are all just simple things (certain depths, killing all enemies) and once you have all upgrades, it isn't that tedious to get back down there everytime if you just go full speed avoiding it all.
Spent many hours getting 100% game completion, as always with your addicting games :P
Only suggestions I can think of would be a height meter, to give some sort of estimate as to how close I am to the ground.
And then also, the cannons... The ones on the ground. It seems they are there to help, but the way they function would almost always end up slowing me down more than they speed me up because of the angle they shoot out and such.
Great game, only thing I would suggest is either adding friendly fire so their attacks hit eachother, or making it so it's not you against the world. What's the point of having navy and pirates if they are both in an alliance against you?
Awesome concept, seriously. Very addictive gameplay.
I understand this was a quick production, but if you expand this, and add more features, this could be amazing.

Umm, "If we had to pay the hospital bill for this guy whenever he crashes..."
...Then we'd have to pay nothing... Unless you were stupid enough to live in America where you pay for that stuff.
I got same bug, if you surrender the battle still goes on in background. So then when you go back in there are inactive doubles of yourself and enemies.
