This is the level of polish I aspire to reach especially for a video-game.
Sayonara does have a core-gameplay loop but it's varied so frequently to meet the high demand of its soundtrack, that it's hard to even describe what this game is? If I say to you it's a runner, you'll be confused upon laser-blasting mechs from a motorcycle packs of wolves not even halfway through.
This game absolutely affirms my belief in abolishing loading-screens, and pursuit of seamless transitions between everything, not just cutscenes but the set-pieces, menus, sub-menus, scoreboards, everything, all the while retaining functionality.
It's not a faultless experience with the occasional level that drags and awkward camera angles, but with it's quality soundtrack, gorgeous visuals, and sheer originality, it's a hard one to forget.
