While I'm still not crazy about it, the combat's a noticeable improvement over 3. The massive gulf in difficulty between boss fights and non-boss fights in 3 isn't as much of a problem here.
Of the main characters, Akiyama's easily the most charismatic. Would've loved an entire game focused just on him being dreamy and doing his weird loan-sharking.
Least favorite was the weepy sewer hitman. Gambling cop twink was inoffensive, but very forgettable.
Was pleasantly surprised by the game's attempts to show compassion for homeless people. A little clumsy, but seems like their hearts were in the right place.
Excellent soundtrack!
