Importaint!
You should slow the DOSBox down (under 100 cycles) before you start the game - the game exits when you press CTRL (and you need to press it to slow the DOSBox down).
You can use the numeric keys - it's easier to do some moves!
This game can also look better, but that can cause it to crash (here's what I've come up within DOSBox, but it's not stable).
