The gameplay is pretty bad, it's the worst of bad action game combat that relies on spamming the dodge button over and over because there's no recovery for it and it just gives free i frames, before easily getting free special burst-attacks because you dodge spam the enemy that lead instantly into dodging again with no recovery (same with leaving or entering guard via holding). Attacking the enemy two-three times before burst attacking can also work to end pretty much anything that isn't getting charge attack>drain attack>attack twice>burst making fights more of a time sink than anything. There isn't the spacing or positioning or rapid decision making and precision of good action games, and not even the timing challenge of mediocre action games. Hold charge attack to cover the distance>dodge over and over before bursting, or land 3-4 attacks depending on boss type before dodging over and over before bursting>3-4 attacks, continue. I played on hard but the bosses were pretty easy, only issue is just not losing interest in continuing as you watch the burst attack continue again. There are other ways to approach it slightly differently, like using the attack combo and then only bursting when you lock blades after getting down to 1-2 enemies, but this method is more unreliable depending on boss due to certain boss moves (and is also incredibly boring, a bit faster but requires attention in a mundane uninteresting sense).
Main character is pretty lame too, incredibly self insert. Story was not interesting, no interesting themes and motivations for characters were messy or boring on the most part. The side characters were used poorly, and the story don't really care about anyone outside of the main 3 chars-but it doesn't develop them interestingly enough either, and instead spends too much time on half developed world and plot beats (that aren't developed enough either).
Presentation wise there was some decent work, combat cutscenes around X and R android flight duels were ok and worked well with the music. Trying to check earlier story chapters resets progress as far as I can tell, which is silly, but this part there might be a workaround.
