finale bug fix
overall nav update

This is final update.

Reduced finale gas cans from 8 to 5 and prevented 2 tanks from coming out.
Place the throwables in the middle of the finale space.
Added supplies in the middle of the bridge.

I was very bad at adjusting the difficulty balance for the game I made. I didn't consider that I knew all the events and structure of my map.

Thanks to the detailed feedback, it seems that the level of difficulty has settled into an appropriate state. There won't be any more updates unless it's a fatal error.

final inifinite tank bug fix

1. navigation bug fix and improvement
2. overall event balance adjustment
3. ending credit bug fix
4. Convinent path added.

Finale wave scripts didn't work. So Infinite Horde with Tank appeared in Finale.
So i just fixed it. Sorry.
