Who did the interface programming?!
When it finished loading I saw something green turning around and around.
After some seconds I found out that I was looking at the ground and my char was spinning.
Some checking brought me to the fact that this game automatically checks all input from keyboard, mouse and joystick at the same time. You cannot disable the input sources in the game!
Although my joystick is perfectly calibrated I could not use it in the game, and I surely won't uninstall my hardware just to test a so badly programmed game.
This is the second time in some years that this happens to me, I don't remember what the other game was, but I thought that after this time nobody will ever make such a mistake.
If the rest of the game is equally programmed, gut look with it, I deleted it after 3 mins.
