Notes: This re-implementation looks and feels so close to the BBC 32K original, it's only really
possible to tell them apart due to the fact that this rewrite reduces the number of colours on-screen and makes the hens the same
colour as the ladders. Hence, the BBC 32K-specific gameplay skills apply equally to the ELECTRON release. Check the gameplay
section for more information. The
CHUCK-2 hack, also provided in the Resource Kit, can be
modified to create custom level layouts.
Review: Essentially, this is visually identical to the BBC 32K release - the only differences being
the change of MODE for the instruction screen displayed whilst the game loads (as the Electron did not support the BBC Micro's
teletext Mode 7) and slightly different colours through the game - notably the hens are now the same colour as the ladders. This
re-implementation was required as the ELECTRON was too slow to run the original BBC 32K release, with it's MODE 2 graphics and
extra coloured hens (though, interestingly, some magazines had letters from people that used the BBC version on the Electron to allow
younger children and people with disabilities to enjoy CE at a less frantic pace!).
Although written in a completely different mode - MODE 5 - the graphics, and gameplay, are identical to the beeb, albeit less
colourful. There are only four colours in use, but this is adequate and the release does not suffer from any colour clashes.
The sprites look good and move well, and the sound effects fit the gameplay nicely. What truly sets this release apart though is
the sheer playability. Pure Chuckie Egg.
