Trolley Follies

puzzle game for Commodore 64, 2018

------------------------------------------------------------------------------
The object is to drive a trolley around picking up passengers and delivering
them to their destinations. 

The track layouts get increasingly convoluted and confusing as the levels
progress. 

Passengers are impatient and your score will be determined by how happy they
are when you drop them off, their happiness is determined by how long they
had to wait.

Passengers left waiting at platforms for too long will leave and that will
actually hurt your score.  

There is a time limit for each level as well as a minimum required score you
must achieve before the exit to the next level is opened.  If there is time
remaining you may continue to pick up and drop off passengers after the exit
is open to increase your score.
