Lunch Break is a game for the Sega Mega Drive/Genesis about workers organising.
The point of the game is to talk with your fellow workers and convince them to join your cause. Unfortunately, you are being chased by your boss, and you need to avoid him at all cost.
The game is written using SGDK and you should follow the steps provided there. If you already have SGDK setup, all you need to do is run:
%GDK_WIN%\bin\make -f %GDK_WIN%\makefile.gen
