Deltarune – the story shown in this game develops in parallel to another part of the franchise – Undertale. In this brainchild of the Tobyfox studio, gamers will meet both familiar characters who have appeared before and completely new ones. All of them will play a certain role in the storyline of the single-player campaign, and will help fill in the gaps in the lore of the universe. The characters are made in the form of two-dimensional sprites with simple animations; while moving through various locations (city, shops, residential buildings, etc.), the camera is located on top at an angle relative to the surface.

The combat system of this brainchild is created in the form of a turn-based strategy, in which the gamer independently decides how to build attacks. This is influenced by the list of available abilities, items purchased from special merchants, and the selected build, created by yourself. During the opponent's turn, the player must choose the direction to avoid the attack in order to avoid damage. You can control it using a controller, native support for which is available in the Deltarune game.

The storyline consists of 5 chapters, each of which contains several different tasks that you need to complete to receive all kinds of rewards and skip further. In addition to battles with ordinary mobs, sometimes the user will be confronted by huge leaders of enemies, who are much stronger and more dangerous.
