1. Does this game's Keyboard and mouse controls work fine?

2. Is there Xbox 360 controller support?

1) I haven't tried the kb/m controls because...
2) It has controller support, but (I'll have to check when I get home) I don't think it's specifically Xbox 360/XInput. I think it's DInput controllers (i.e. Xbox 360 triggers can't be directly mapped). I'll update it after I get home and confirm. =)

Thanks as of this post it says you posted 30 minutes ago.

How long until you arrive to your home to confim it?

Also I take it Keyboard and Mouse is...........you know :P

Got to leave early due to the holidays. I just tried it out. There's a Settings application you can run to activate the controller and it does have support for the XBox 360 controller. However, none of the key icons change from the kb/m controls, so there is a little guesswork involved. But, it's not too bad:

LS = Move Larry
RS = Not used
X = Enter (will also make Larry fart when no options are currently selected)
B = Examine
A =
Y =
LT & RT = Rotate camera
LB =
RB = Open and close Little Black Book (in-game journal)
Start = Digital camera
Back (hold) = Show stats
D-Pad = Cycle through available objects/people

The buttons correspond to a set of circles in the lower left that contain icons showing the actions, in the same positions as the Y, B and A buttons (but you use X instead of A, go figure). The A and Y buttons are context sensitive, activating when a certain object or person is within range.

I haven't been very far into the game which is why I haven't yet filled in the Y, LB and A buttons. Regarding the keyboard and mouse controls, there's a layout in the manual with a number of keys performing duplicate functions. Mostly, the controls don't look too bad, but I usually prefer controllers.

I can't rebind controller (Xbox One pad) buttons. "Analog Axis 1" and "Btn 3" are likely controller input fields, when I select one and press a button on my controller nothing happens. I can rebind keyboard keys, but not mouse.

The default configuration is typical for games with no native Xbox controller support, the game uses triggers for camera control for example.

Have a look at my post here, it might just help you with this some if you want it to play nicely with a controller. You may need to adjust them some for Windows though.

However, many of the minigames actually play better with keyboard.

Care to elaborate? If I have to switch to keyboard with some minigames non-functional controller doesn't matter that much.

Well, its been a a couple of months, but a much repeated minigame is where you direct a sperm through an obstacle course while Larry goes on and on about some bullshit, collecting hearts and trying not to say the darnest things (some of which are funny and worth hearing). This is one minigame I found much easier to clear with the keyboard than a controller. There were some others too; I'm not entirely sure how to play quarters at all, but in any case it seemed much easier to clear with the keyboard. I'm sure you can clear them with a controller too.
