The game involves the player solving puzzles by interacting with the environment through the use of a text parser and was an example of Falcom's technical know-how at the time. Every contemporary Japanese adventure game released for computers during this period would draw its graphics line-by-line and slowly fill in the colors, a long process that would need to be done anytime the scene changed to a new image. Demons Ring, on the other hand, could transition to different images in under half a second, a feature that was heavily advertised by Falcom and something that would eventually become a standard for the genre moving forward.External Linksæç”»é€Ÿåº¦ã®é€Ÿã•ã«é©šã„ãŸæ—¥æœ¬ãƒ•ァルコムã®ã€Žãƒ‡ãƒ¼ãƒ¢ãƒ³ã‚ºãƒªãƒ³ã‚°ã€by ä½ã€…木 潤 (Akiba PC Watch, 2019).List of Falcom Game Release Dates 1984-2011 (Kiseki Fandom Wiki) - Transcribed from the "Falcom Chronicle 30th Anniversary Book."
