Deltarune

Deltarune is a role-playing video game developed by Toby Fox. The player controls a teenage human, Kris, who is destined to save the world together with Susie, a monster, and Ralsei, a prince from the Dark World. During their quest to seal the "Dark Fountains" prophesied to end the world, the group meets the inhabitants of the "Dark World", some of whom try to stop them. The combat system is based on bullet hell attacks the player must dodge. Similar to Undertale, enemy encounters can be resolved peacefully or through violence.
