Hey, Rocket here, the character artist and animator for the game. Actually, we planned on having SFX, I found some nice stuff, but we didn't have enough time to implement these before the deadline. But that's something we're considering for an update. As for the music, yeah, we didn't have time to find a composer to make us a custom soundtrack, hence why I grabbed stuff from the Free Music Archive. But maybe in a future update? Not sure yet, but that could be fun
