To be honest, I prefer the mechanics for this so much more than the original game (which is quite good in its own right), that I struggled to not knock a star off for "making the good core game the expansion so I'd be forced to buy the inferior expansion as the base game".

Also, music-wise, The Amaranth. Sooo addictive.

I think the only legitimate complaint I have is that I prefer the "you haven't beaten the game" menu screen music to the "you've beaten the game" menu screen music and, unlike when you install Cuphead's DLC and get a new title screen, there's no option to switch it back.
