Or the snake one called Nibbles - my 6th grade computer class teacher had made modifications to it adding levels, etc., and had his class play with what he had created. I was just starting to learn Qbasic at the time and he wouldn't let me have the source code :(

Perhaps he was hoping you'd write your own, or find the code? Weren't the games plaintext?

He used QuickBASIC to compile it into an EXE and that was the copy he gave the students to play with.
