I finished it with 100% and would give it a 6 or 6.5/10 too, the overall gameplay is just very basic and never does anything interesting, the best it has to offer is the painted backgrounds and a few really well executed boss fight.
I'm hoping it gets something cool as DLC though.

>Lace can absolutely anti-air you for two masks of damage and she does it all the time.
her anti-air is her most telegraphed move, she only does it out of neutral or as the 2nd or 3rd part of her dash combo, idk why they decided to do it like that because she's a sitting duck if you stay airborne, even triggering her parry is to your advantage
