The game contains 2 - 3 locations without text and a few graphic inconsistencies but you can complete the game in its current format.
The game still contains its play testing cheat - type 9 as your choice and you are taken to a location select screen - enter the location screen e.g. A20 and it will take you to that location. I therefore recommend you keep a pen and paper with you as you play and record which screens you visit.
Hope you enjoy the game as it is.
