After a bit of review, the following bugs in the demo have been fixed:
-Number of keys to collect was not mentioned. Now, along with the opening, there is an on screen mention to collect 3 keys.
-With each key collected text will appear on the screen listing how many keys have been collected for a few seconds before disappearing.
-Keys have been slightly enlarged so as to be able to be seen better.
-Message during loading screen gives hint to assist player in navigating the area.
