There are some nice little graphical interludes, although the sound can get a little annoying.
I counted 23 locations. The puzzles are fairly easy, as you would expect for a game aimed at children, but they do all make sense.
Nice large text (MODE 7 double height) in different colours.
Fairly basic but no problems.
The old school BBC graphics do add to the atmosphere of the game.
I only found 2 instant deaths.
Fine for the intended audience.
A fairly basic game, but ideal for kids.
