Cool game
but just for future: make hitboxes of stuff player be aiming at bigger. It is hard to aim tiniest little door knob in galaxy especially without crosshair. There are nothing next to it anyway, make collision half a meter wide. Second thing: player need a way to know for sure the object is interactable at this moment. For example i really was about to stuck, because doors are active only when you pointing at a knob and only when you don't hold stuff in hands. Why?
It is applicable to any game - give players a little bit of aim cheats and a way to be sure the game didn't broke
