@Urmomsigma what makes your question unique is the fact of who made the game. Toby Fox was popular because he created music for some of the most popular video games ever made. He created music for Pokémon, Super Smash bros, and Deltarune (most popular among the age groups from 8-14). And the answer to your question for the game is 2015's game Undertail. Toby Fox was actually surprised by how successful the game became.
