how is aquapazza, is it similar to other japanese anime fighting games like persona 4 arena, and blaze blue?
Nothing like them, and nothing like Examu's other game, Arcana Heart, to boot. The game's much slower paced, like Street Fighter with flashier (yet still relatively short) combos, A-B-C attack chaining, assists, and air blocking - think Vanguard Princess, if you've ever heard of that. For what it's worth, I like the game a lot. It's probably the easiest non-Divekick fighter out there to just pick up and play. Some people might complain about the balance, and you admittedly will face lots of Chizurus and Tamakis online (NOTE: the netcode sadly isn't very good D: ), but I don't think it's as huge a deal as some make it out to be.
