So I have updated the controls... And changed the cage. I think it should be a lot easier to use now. Comments welcome...Please :)
W,A,S,D, and arrow keys to walk
Space to jump
Left click to shoot cage, then middle mouse to lock cage around the ghost. If you want the cage to disappear middle mouse again.
"Portal" button drops portal object, when you push the trapped ghost on top.. it will disappear.
"Totem" switches to shooting totems that freeze (scare) ghost.
Um that's it for now... Next some ui stuff (...boring)
