Square's third and final text adventure game was called Alpha, released in 1986, and tells a science fiction story in the same style as The Death Trap.

An agent named Benson is sent to B country in order to rescue the doctor and avert the new threat to world peace.

Masashi Miyamoto, who founded Square in September 1983, believed that it would be more efficient to have graphic designers, programmers and writers work together on common projects.

Upon Square's inception, Miyamoto initially hired as their first developers university students Hironobu Sakaguchi and Hiromichi Tanaka, and a few others.

[6][4] Sakaguchi was also a scenario writer for The Death Trap even though he too was a part time employee who had just left university.

The graphics team consisted of Hiromi Nakada, Miki Yukinoura, Miho Imaizumi and Tomoko Saito, while Yasuyo Ide held the position of data editing.

[1] During this period, The Death Trap was one of three games that made within two years, which was a fast pace of development.

Hironobu Sakaguchi, Hiromichi Tanaka, Harunobu Kato and Hiromi Nakada continued developing games for Square, while the rest of those credited left.

[2] Project EGG, a licensed emulator for home computer games, included The Death Trap, Will, and Alpha together in its limited edition "Classic PC-Game Collection" on September 8, 2013, alongside Cruise Chaser Blassty and Genesis—other Square games released between 1984 and 1987.
