=========== HANDLED ==============
- add ifdefs that change car color?
- Try progressively slower steering?
- compile time option to choose how many maps to include (for platforms with

@ -243,6 +243,9 @@ A few tips for making maps:
not even being noticed by the player.
- There is a special "mirror" block that's very useful for creating
8-symmetrical structures.
- Add more visual detail only where it's worth it, i.e. where the player will
see it, for example the near the start instead of a section that just quickly
passed at high speed.
