I recently found your game and I think it's great! I've been looking for a 16:9 ratio version and haven't found one. Is it possible to make a 16:9 version fitting modern monitors so that more of the maze could be seen?
If you're still interested, you can now press F8 at any time to change the screen format, from 5:4 (approximately) to 16:9. See other changes in the game instructions.
