I was googling but i can't find mod which would enable to play game with modern key controls. Like W,A,S,D and mouse control. Does this exist? This is the only reason why i can't play this game because controls bother me very much!

Don't know if you figured this out yet. It's really more meant for keyboard only (similar to Alone in the Dark). You may be able to remap the arrow keys to WASD using Dosbox's Mapper function (https://www.dosbox.com/wiki/Mapper). As to the mouse, unless there is some separate program to remap the directions of the mouse to be arrow keys, I can't think of anything that would help.
