Public library of things I wrote on the ZX Spectrum
This was an editor for the game Bumpy. The original game can be downloaded at the World of Spectrum page.
There is also a youtube walkthrough of the game, to see how it works.
My editor allows you to create your own levels for the game. I originally wrote it hoping to get it published in Your Sinclair, but it went out of circulation shortly after writing the program, so I never ended up sending it to them. For those interested in Your Sinclair, see this memorial site.
