Just beat it, gotta say though, if you take away this games presentation and it's not really that good.
-Stat grinding in a beat em up
-R1 attack can't be used out of stun
-Lack of invincibility frames leads to cheap stuff
-Excessive blocking
-Shop descriptions AFTER YOU BOUGHT THE ITEM.
-Moving diagonal sucks, end up using stick due to dash
You can overlook some of it in co-op (like the pitfall sections cause its funny) but for the most part the game is pretty painful. Difficulty curve was also pretty bad early on, then you out-grind it and button mash through the rest of the game, should have just tuned the difficulty levels right and screwed the whole stat system and only have consumable items if anything.
But hey the game looks and sounds great
