Not too bad for my second attempt.

I'm not as happy with this one as my first one. I wasted a lot of time struggling with AI and terrain.

The controls aren't perfect, the physics and the difficulty are a bit odd, and it's not the prettiest of games.

But I learned a lot from this, definately worth the time.

Edit:
So I actually had a 1 instead of a 0 that made only old players see the tutorial. So I think that covers the Bigfix later rule.
Here's a psudocode of the problem:
If (you played the game before){
load tutorial
}else if (you never played the game before){
load level 1
}
