I'm not talking about making a 3D game engine. I'm just talking about using a 
few OpenGL commands to:

- blend images on the screen.
- rotate the game screen as you want.

As far as I understood, while the player moves, you have to build the part of 
the world he will see.

If you succeed in doing that with OpenGL, all the images will go to the 
graphic card, and so blending and rotating will be fast (and I think they are 
now supported by all free drivers).

Otherwise you will never go faster than 18 FPS.

Yes, programming an Android application with Gambas would be cool!
