I only feel vibrations when getting hit, and even on the highest setting it can be kind of weak. I haven't felt any vibrations anywhere else in the game, which seems bizarre to me considering that previous doublefine games going all the way back to the first Psychonauts have always had excellent force feedback support. Rad, in particular, had excellent force feedback support.

Additionally, adding vibration to the vibration control in the menu would allow a player to easily check if their vibration is working, as well as instantly be able to feel how their current setting affects the strength of their vibrations.
