"Deltarune", like "Undertale", is a role-playing game that uses a top-down perspective. The player controls a human named Kris and has to complete objectives in order to beat the game. During some parts of the game, the player is allowed to choose attacks of other characters in the game. Combat is similar to most normal turn-based role-playing games, choosing from a set of actions such as "Attack" or "Spare". While the game is biased towards avoiding fights, one of the party members, Susie, would rather attack enemies than spare them, so the player has to choose actions that will stop Susie from hurting enemies if they want to show mercy. The game also has TP (Tension Points), which allow team members to use spells such as "Pacify".
