No idea why people love this game... it's a tedious experience with little reward.
Sure, it looks kinda cute, sounds kinda nice, the dynamics are kinda neat... the first few times. Then all of it gets grindy fast.
Mechanics such as... Press and hold the key to do a pull-up, let go after Ringo goes down, which takes forever, and do it over again, the more pull-ups you can do, the longer it takes in game and in real life! Sounds like fun? Fighting gets tedious fast as well. Press some keys so you grind your way to higher attack and defense stats. Real exciting. These don't increase during martial arts training, which makes no sense...
"Minigames" like pool where you don't do anything except position your character, press a button, and see if you get a ball in the hole - no player skill required - at all. Just grind to up your in-game skill level.
Not like you're told do much anyway, starting with the non-intuitive main menu. Only controls are partly explained in the tutorial, not what you have to do or how. Sure, you can figure it out by yourself, grinding endlessly and trying to figure out what to do at what time to trigger which unrewarding little dialogue. More chores - write down or memorize which shop is open when, which character is where at which time.
Or you consult a guide - made by users, of course, not the devs. And then grind according to instructions. More fun? You don't get rewarded either, except for some dialogue and achievement there's no reason for you to care about.
There is zero userfriendliness - you don't have an inventory. Can' skip animations. Can't skip / fast forward time while reading. Leave the screen acidentally through a door - all the pickups from downed enemies are gone. The bag you wanted to sell is gone as well. Rinse and repeat. Just to make it even more tedious.
