Origionally pixelled in 16 colours, i repixelled it to 128 colours for CD version.
The lava was animated using colour cycling, you can bring it into deluxe paint 2 and set up the 11 lava colours as a range and play the cycle to see how it would have looked. make sure not to set the cycle too fast. Cheap way of having animated lava in a level. | 
Hi showtime,
