I just finished a qbasic game and need some beta testers.
Anyone interested? It's called Mansion and the game is
available at http://www.geocities.com/hawk360/mansion.html

The only bug I've found is that the first position of the character in level 2 and level 4 is very odd. Then, when you move it, it will readjust.

BTW, when you lose, maybe instead of ending the game you should put an option to restart it or re-enter a password.

I agree with Radiobuzz.

Move the door around then where you start in the game.
