And because it was designed as such, comparing this to bandori can't be avoided.
Difficulty doesn't scale that much, if you play Bandori, Deresute and all other rhythm games in maxed difficulty you'll find SBR:FaL a bit too easy. It's fun for casual players but not so much for veterans.
Despite these flaws presented in the game, my real honest take is that is has a lot of great songs to pick (not in term of quantity but it's more to quality), one reason I like this more than Bandori. Sure, Bandori has several good originals and huge amount of cool covers but it doesn't stand much chance to SBR's songs, it's just my opinion so please take it with a grain of salt.
Is this game worth your time? Maybe, if you like cute kemonomimis and great songs then this is the one for you. But if you're a rhythm veteran looking for challenge, you can skip this title until there's a real challenge coming to the game.
