• Acknowledgement page
• Instructions
• Drawing ghost in all visible areas now
• Drawing gems in all visible areas now
• Added counter for steps taken
• Added effects (visual and sound) when being attacked by the ghost

Todos:

• Highscore list and save

• Showing Exit in game more prominently
• In-Game options for restarting or aborting map

Maybe:

• Add larger map, including healing item
