Hi again!
I played with your game with a more powerful computer. I’ve got 20 FPS. You have been doing an excellent work! It becomes more pleasant and more interesting! The flamethrower is really fun, the gameplay becomes nicer but maybe you could find a better keyboard configuration to allow stafe. It is a bit difficult to strafe by maintaining pressed the left button of the mouse :(.
On the other hand, maybe you could reuse humanoïd models to improve the animation of your main character. I need to explain what I mean : in an extern module of my game, I move a MD3 model which has been drawn by someone else. As the vertices have been computed thanks to motion capture, it is more realistic. Maybe you could find a model of man with realistic movements as I did for this imitation of Lara Croft (look at the screenshot on the discussion concerning my game). If you need a MD3 loader, mine is still working and the source will be put on my website in a few weeks. I know that your priority is to improve the gameplay… do as you wish and thank you for your game.
