Aka: The Tale of Old Man and Ninja Hacker.
A small game made for Ludum Dare 27. (Ludum Dare is a monthly game competition.)
The game keeps swapping between the old man and the hacker – they occupy the same position, meaning the old man is brought on a wild adventure into very unlikely places. Both characters are needed to make progress.
The concept is a little flawed because of all the waiting, though. And I didn’t find much stuff the old man could do.
