Howdy - just purchased this game but is not fully functional. Using chrome browser btw.
(1) Score or any "game over" related text/ variables not displayed (plus wrong screen orientation)
(2) when projectile and alien ship collide the following error message is displayed;
"Cannot create an instance of the object type 'Sprite19m': there are no instances of this object anywhere in the project. Construct 2 needs at least one instance to know which properties to assign to the object. To resolve this, add at least one instance of the object to the project, on an unused layout if necessary."
