Just tested the game a little bit more and I really like it.
But there more things I want talk about:

1. It would be really cool if you can strafe your plane left and right.

2. Fog does not work on MorphOs 3.8 with Radeon 9600XT
(on 3.7 it also did not work).
Here a screenshot of the game with enabled fog:

3. It would also be cool if you can look left and right.

4. VBOs do not work (see debug log)?
r300.library: Performance warning for task "Wings-Battlefield": Disabling VBO rendering due to incompatible parameters

5. Far future: Please reuse your engine to realize a sequel to
The Shadow of the 3rd Moon
