This is a homemade game created using the game creation tool "Click & Create." It was released on the Japanese file-sharing site Vector in 1996 and was also featured in the computer magazine "TECH Win" at the time. The creators are "Sankaku Onigiri & Tomo-chan." Apparently, it was co-created with the author's third-grade son. The game was eventually deleted from Vector and seemingly forgotten, until 2008, when someone accidentally discovered the game's data and posted a gameplay video on Nico Nico Douga. The game's strange gameplay and music, as well as the protagonist's bizarre behavior upon death, became a huge hit among a small group of people, and at the author's request, it was re-released on Vector.
