Well, I wasn't quite able to perfect the slider bars, so you'll have to make do with clicking on the bars - this will put the marker on wherever you click on the bar.
Aiming is a b***c, especially when you have 8 enemy pie boats heading your way.
The 3D simulation is improved, with the pie going almost strait up if you put the elevation on maximum.
I'll reveal a game-play tip for making this version easier to play - using it, I got a score of over 300 and remaining ammo of just over 160.
You might want to have a second person control the fishing pie as well - aiming and trying to catch pastry crates really is pushing it for me!
