Deltarune
Deltarune was developed by Fox in GameMaker Studio 2. The game introduces a new battle system influenced by the Final Fantasy franchise, contrasting with the original game's combat system (which was inspired by that of the Mother series). Some of the music in the game remixes much of the soundtrack of Undertale, but most pieces are new. The main game uses sounds from EarthBound, while battle music is similar to Breath of Fire III music, and even Lancer's theme is similar to J.A.K.Q. Dengekitai's opening theme. The game also has many similarities with Undertale in the name of characters, for example, Ralsei (one of the main characters) is an anagram of Asriel (a character from Undertale) and Kris (the main character from Deltarune) is almost an anagram of Frisk (the main character from Undertale). The name of the game, Deltarune is an anagram of Undertale. Temmie Chang, who helped as artist in Undertale, served as the main artist for the game, designing characters, sprites and animations.
