There shouldn't be any zooming in and out as the input for that was not connected, if anything it's probably that the camera would have had an obstructed view of the player so you probably had your camera too low, if you look down onto the characters it probably works better. But yeah if you walk near a shelves or under the clothing racks the camera gets pulled into the character really easy in the more cluttered spaces of the level. Something to polish it up for us could have been making it so that camera deocclusion stuff doesn't apply to most shelves or it pulled the camera up instead of toward the player.
Yeah I've only played it with a group of 4 so far but it was pretty fun, I think it gets more fun with even more people.
Thanks for the feedback and thanks for trying the game out.
