Impressive work creating a 3d game for 3DO in this tight time-frame, but sadly the game have many issues.
Sometimes the collisions of the particle gun don't work, I think that this have to do with the pitch of the vehicle.
The pitch of the vehicle seems to me, that for some reason is on a global axis and as a result it may appear and as a roll or in-between. I personally believe that the pitch of the vehicle was unnecessary.
Maybe a better option can be to cast a ray from the centre of the camera and then use the collision point to shoot the particles from the "gun" of the vehicle. I believe this will make the game more enjoyable.
Another thing that I believe can improve the experience is to create a little bit more visual cues.
For example, I played the first stage (0) many times and even thought I got in the dark areas, I never found the other room. I found out about it by watching your video. Also, even when I watched the video seemed to me that something was blocking my way to reach the room.
Over all, impressive work on the engine, please keep it up.
