Love it! Brings up so much nostalgia from the days of programming on my old TRS-80. But is it really a maze? Once you start, you don't seem to get much choice of path...

For anyone not familiar with the TRS-80, who finds the code somewhat weird.. the BASIC implementation was written by Microsoft. Only the first two letters of variable names were significant. Although interpreted, the ROM tokenized typed lines, meaning it didn't care about spaces.
This led to such gems as:
FORK=10 TOMATOES STEP LADDER
It's a (neat) graphic trick.
