I used Ease of Access Center in Windows to control the mouse via the numpad to get past the really annoying ones, getting past those parts was worth it.

    for i in $(seq 50) ; do
        eesh warp rel 0 -8
        sleep 0.1
    done

// yes, I still use e16

On the narrow stretches you can cheat by right-clicking at the entrance (so you have a context menu and the game cursor freezes), then moving to the far end of the narrow section and left-clicking to release the menu. The game cursor will jump to the new position.

Agreed. Fun game, but these levels absolutely kill it for me. Wound up enabling mouse keys in windows to use my numpad to move the cursor in a straight line...
