So I just picked up bastion and played about an hour of it. There's this weird bug(?) where if I touch the left stick even slightly (literally i could touch it with a feather and it does this) my guy starts walking left and doesn't stop until I use the stick again. At first I thought that my controller is broken because it seemed like classic broken controller stuff. Then I went and tried to reproduce it in MvC2, Assassins Creed 2 and MW2 and couldnt do it. 
 
just what

Mine does this as well.  No idea what causes it but it's mighty annoying when you just end up running off edges for no reason.  

Wow I thought it was just my controller same here maybe its a small glitch

Alright I looked into it and theres something called deadzones in 99% of the games that prevent this from happening. Basically the stick on your controller loosens naturally over time and you might get this kind of behavior if the game doesn't have these deadzones. Not a big deal wont stop me from playing the game but should be easy enough to fix with a hotfix.

Same issue here, really annoying when it walks you over an edge. 

Same here, but my controller is pretty bad and is from 2006. So I didn't think it was a glitch.

I have a brand new controller and it doesn't happen to me. Just seems like it's what Phonics said, with it happening to more used controllers.

I have not had this issue. Could be that the deadzones in Bastion are smaller than in other games, considering my controller is fairly new.

Didn't notice it at all from start to finish. Maybe I will play around with it tomorrow.

I have two new controllers and it doesn't happen to me. It would probably would be a very easy thing to patch if it is affecting enough people.

I can usually replicate it if I flick the stick in the same direction a couple of times. Using a fairly new controller that came with 360 S bought back in March this year.

I wasnt able to replicate this with any of my controllers including my xbox launch day wired controller( the only part of my first xbox that still works)

ive had this happen a few times.. not a huge deal but annoying. 

Has happened to me as well, but my controller has done this in other games in the past. Not as much as in Bastion though.

The game just might have a really small dead zone and you're controller has a bit of a loose stick. Try using a different controller.

I've got the same problem. Caused death by falling off the map quite often, I must say. I hope they can fix this without much trouble.

Ah, I thought it was my controller (it kind of is, I know, but I haven't had this problem on my new black controller until Bastion).
