You know you did good when the biggest gripe people have with your game is that they want more. The vibes are immaculate, the way your abilities synnergize with the music itself, the funky designs, and the fun of trying to synnergize various abilities, alongside having a clear yet complex strategy to it all just combine to an incredibly fun experience.
You could've totally gotten away with making more stages or an endless mode without adding new features. What you already have is enough for so much.
Well done.
