Deviantart-level presentation with fanfic-level writing and top-notch-cringe amateur voice-acting makes this demented piece of game a really fascinating camp work.
In it's core it is rather usual score\3-stars–grind rhythm-game in jrpg style without any of annoying jrpg timewasting.
"Level-design" or "gameplay" is very sound, narratively speaking - melee strikes require precise aim with swiping, while ranged ones require hitting moving targets on time.
But this game is rather strangely ported, and i don't know if it can be fixed. With mouse most basic actions become much harder to perform, especially on higher difficulties, which combined with high resolutions (targets remain the same size while spacing increases) makes it really difficult. But with proper touchscreen monitor and ancient 1920x1080 resolution this game is pure mechanical joy to play. Still this is a pc version and touchscreen monitors are rarity, so no excuses.
Overall it's rather enjoyable rhythm-game with all of squalor in fascinating trainwreck of presentation.
