M I K U?
I think I’ve been summoned I love vocaloid lemme help!
So I see everyone is talking about barrier art but if this is a platformer you could try putting the platforms into the shape of a vocaloid as well! You could also have summits dedicated to specific vocaloids or songs. Up to you, good luck on your game! If I missed anything let me know.
You could also make it both survival and don’t look down, like a knock back style game!
