The characters I could see as different skins except for Reine which got kinda gypped. As for the first 2 extra levels those were just harder versions of the same stage while Gura is a completely different person in Hololive and one of the more popular ones so I was disappointed because I like Gura and wanted her to get her own stage rather than a reskin of the same stage Irys got. The spikes randomly thrown into different stages were not there before and were only put there in this update and the pink clouds were only in red heart. He had a completely different feel and platforming style as well as assets for each of the stages and each new stage felt fresh and exciting and kept me coming back for more. until the resent update when he seemed to reuse things a little more than usual. I know he has the ability to do it because he has done it with so many more stages he just didn't do it with Gura.
