It's a fantastic short game, with a creative concept in my opinion.
Only very minor gripe I have is the floatiness of jumps. I find it slightly awkward but that's really my own preference. It's a very fun game nonetheless, it's good-looking and my mind was blown away when I found out the main melody changes with the character.
Watch me have too much fun with the character select screen in my showcase video:
