Finished - roughly - the first seven levels of my game-in-progress, a folky themed old style shooter game, so I thought I share it with you guys for some feedback.
I hope it is forgivable to not share the .blend file, but I use 2.61 and I have no idea how it all would look in other versions of Blender, plus, I am kind of embarassed of my scripting and logic brick setups which might seem very amateurish.
Arrow keys - move
Z - select (menus)/shoot (levels)
X - bomb (if you have any)
Shift - focus (slower movement speed for precise moves)
