British transport at its best...

Planning on a nice stint of coding on the train home only to find train delayed and standing room only.

Put in some late hours tonight to make progress on "Bunker!"

"Bunking" of "Bunking-off" is English slang for missing school.  As Ferris missed school 9 times this is my game.  Therefore "Bunker" is about covering your tracks.

You need to pass over the numbered squares nine times to erase any record of Ferris' missed attendances.

Clearly still missing a lot,sound, music, enemies, scores, lives etc.  The gap on the right is where this info will go.  Using some Mario inspired pipe graphics that are freely available.  Mental note to add reference to source of graphics..
