Try Using Ctrl Instead of Alt

Alt causes problems in the Unity editor with selecting from the menu bar.

Try to use ctrl instead.

This is implemented in a branch called ctrl.

The only problem I've come across is that you could previously hold control and press a direction to interact in that direction. This no longer works, because ctrl changes your movement move into sneaking instead. This doesn't seem like much of a loss. You can just interact with 'e' and then choose a direction anyway. I think this was a remnant from old input code?
