I'm making this guide using my own setup for my keyboard binds. It may not work so well for everyone, but that's fine. The real reason for this guide is to help people with figuring out what does what so they can bind it however they want.

PS- As of (3/18/2017), this guide is incomplete and is a WIP. Also, there are bugs/glitches within the game that have yet to be patched (which one should expect in these earliest days of its release). One particular bug is when certain keybinds can overlap with other commands while others reset to default.

The controls and keys are as follows:

Movement = WASD
Menu Navigation = UpArrow,LeftArrow,DownArrow,RightArrow

A - Jump - Space
B - Dash - LeftShift
X - Weak Attack - LeftClick - (i-key)
Y - Strong Attack / Toss (Equipped) Bombshell - RightClick - (o-key)

RB - Guard/Camera Reset - R-key
LB - Transform - Q-key

? - Lock On/Taunt - UpArrow
? - Limit Break - DownArrow (Does damage to self)

? - Tech List - H-key

Start - ? - ?
Select - ? - ?

L-Analog? - ? - X-Key(?)
R-Analog? - ? - NumPad2(?)

? - Camera Up - NumPad8
? - Camera Down - NumPad5
? - Camera Left - NumPad4
? - Camera Right - NumPad6

Start? - Pause / Skip Cutscene - LeftTab or Esc ----- [I'd bound it to the escape key but LTab does it too, in fact sometimes ONLY LTab will do it. A bug no doubt] - (To skip cutscenes, you must have that option enabled from the settings menu)

--------------
Commands:
LB = Ninja Transformation - Restores Full Health - (Requires 1-Scroll)

LB + X = Secret Ninja Art 1 - (Requires 1-Scroll)
LB + Y = Secret Ninja Art 2 - (Requires 2-Scrolls)

LB + B = Ultimate Ninja Art - (Requires 5-Scrolls + Low Health + Must be unlocked for each character)

RB + Y = Frantic Mode Initiation (Once initiated, use the Xbutton (i) or (o) key to activate)

A then RB + B = Fusion Ariel Rave - (Requires an Ally being present)

A then B (near wall) = Wall Running - (Must be near a wall)
A then B (near wall) then X or Y = Wall Running Ambush Attack (Must be wall running BEFORE trying to attack)

A then B (not near wall) = Air Dash - (Jump then dash, simple)
A then B (not near wall) then X or Y = Air (Dash) Attacks
A then X or Y = Air Attacks

L-Analog + R-Analog = Summon Helping Hands in the Dressing Room = X(key) + NumPad2
(After Summoning) L-Analog OR R-Analog - Smack! - X(key) OR NumPad2
WASD and NumPad8,4,5,6 = Position Hands (Left and Right respectively)

Other way to use helping hands in the dressing room to X + B in keyboard
1 and 4 grab
X and B again to slap
L to return to viewing mode

When the heart gauge is filled while the Helping Hands are active, (right click) her hands and she will offer to hug you. (Right-Click) again and she will prep to kiss you. Line up the lips cursor with her mouth and press.... X (i-key) then you'll kiss her.

Standard Setup (NOT mine):
L-Stick = WASD
R-Stick = TGFH
D-Pad = Arrow Keys

X Button = I
Y Button = O
A Button = K
B Button = L

L3 = X (key)
R3 = B

L-Bumper = Q
R-Bumper = R

L-Trigger = 1
R-Trigger = 4

START = Tab
BACK = Esc

That's all for now, I hope this is helpful to you. Lastly, if there are any details you think I missed or made a mistake on (outside of what keys I use for MY playstyle), please let me know. This guide is here to help people learn how to play (myself included), so if you know something, share it! Thank you!
