Well, I will try it tonight, and will write more about it. So far, this game is very chelanging, but thanks to save-state I was able finally to come to the last level.
Last night I finished Arena level, and finally I saw what final boss looks like. Will take me some time to explore it first and then try to kill him.
Also, humor in the game is great.
I used to have Amiga version of the game, but it was hard to play on gamepad/joystick while for some commands you have to use keyboard.
