A nice twist on relatively easy hacking minigame from Nier: automata, offering a glimpse to what a hack and slash gameplay could looks like with the intensified bullet hell minigame.
I found route B, the light sword, to be quite cheesy at time.
Route A, the dark sword, however is whole other level. Continuously reduced health with life leech attack turned a simple minigame into an insane bullet-riddled Dante Must Die difficulty, especially on later levels.
One of the most intense and enjoyable time I ever had.
