How to Play
You need to adjust the gameplay speed right in the start menu depending on your CPU, as this game doesn't do it automatically and can be too fast at first. But adjusting the speed can fix everything. The game is designed to run on DOS, but it works perfectly on Windows 3.1, 95, 98, and Me. It also works perfectly with DosBox.
