LUFTRAUSERS is a shoot’em up, or an aerial dogfighting game, where you get to make a plane out of 3 parts (weapon, body, engine) making up 125 combinations, each with a different audio track (I assume they have 3 layers/parts, for each bit) – I personally like the nuke body (where you blow up when you die, but take extra damage from collisions) the best.
This game is elegant, there are a total of four buttons you can click: Right, left, up (accelerate) and “Shoot”. Nothing else. Actually, the game has 6 buttons. Right, left, pressing on accelerate, not-pressing on accelerate, pressing to shoot, and not-pressing to shoot. While it seems weird for me to note these, as we don’t talk of “not shooting” as a button in most games, there the choice is often what to shoot, or how else to circumvent an enemy (Stealth games).
