There has been a Total Blackout, a mysterious facilty seems suspicious to our young Sack person. So they investigate! Restore power on the first two floors and see if you can find two collectable Jars (they require some degree of logic to find.) Where ever you see a question mark, start looking. It is short because it's a demo but there are some cool features and puzzles with a fair level of challenge, give it a try and let me know what you think! I have just updated this level 3/18/14 I believe it is easier to play and all around just a little better now. Make sure to play it in a DARK area as it is intended to be seen that way, and for best audio experience wear Headphones.
