hey I'm really glad that you guy are giving that much attention to controllers, I have always prefer to play with it, sorry for my poor english /:
1- I'm using a ps4 controller
2-yes
3-yes it works, but some options are missing like the R1 says that has nothing on it but in game it makes you se further
4-i don't know if i'm missing some or now you only can push zombies if you are near them, before the push and using a melee weapon were on diferent buttons, the same applies to stomping on zombies
5-there are some windows that aren't interactives with the controller, like the one that show updates and the one with the cars tuturial
6-the first time I tried it crashed the game, but that only happened once
7-I prefer the it is now
8-every time i close my inventory my character makes the push animation and that stops any other interection, if you try to open a window while sprinting the character some times breaks the window instead and passes through the broken glass, cutting himself
9-no, the game ran the same way as always
10-pushes and stomps on different buttons and the problem on closing the inventory
thanks for the opportunity for helping, I love the game and I can't wait for the animations
