For some reason this didn't run on Brave except when I disable the built-in blocker. It does run on Chrome (even with ublock) though. So I assume it's because of some Itch stuff.
Otherwise, yeah, it's a suika clone. The music looping is somewhat annoying since it has a large silent part at the end. The balls are also a bit too frictionless, though I don't have much experience with suika clones to compare.
