In at #73 it's a magazine listing type-in game called "Bombed: The Gate Part II" from David Hopkins. This game was a sequel to a previous type-in listing from 1989 called simply "The Gate", but in my opinion the 1991 sequel is a superior game in terms of gameplay. A time-constrained maze puzzler with added dynamite, it's a joy to play and all the more impressive for being a non-commercial release. Enjoy!
