I'm choosing to imagine this as a canon buddy adventure for these two in the events following the game Hades.
Great graphics and framerate, especially for WebGL, I'm always battling with it in game Jams since I'm 3D-focused. I especially liked the minotaur character.
My suggestion would be to give these two a little banter in each level. I think that could be really fun, offer the player hints, tell some story, a lot of possibilities there to flesh out the experience.
Nice work!
