I have been trying to remember the name of a certain computer game for about 17 years now. It was a dos game in black and white where you control a character that is static using the keyboard. You went around solving puzzles and collecting keys to open doors. There was no menu or instruction screen. you walk into enemies to fight them but normally the best option was to avoid them. I used to play this game in computer class in elementary school. The only games they had was this, Oregon Trail, and Yukon Trail. Someone please help me with this. I have been able to find no mention of anything like it in years of searching the internet.
