The mess of source code that made up my Sensitive game is now availiable from download from my site (its in among the code for my old plug-ins).
Unfortunately, as I had to get the complete thing from a backup (new hard-drive y'see), bits of code are missing (mainly the interface to a routine to convert scancodes to ASCII), so it wont compile directly - remove those bits and it will, but you wont be able to enter a name for the hiscore table.
If you do use the idea/source code, dont forget to mention me & the originating author.
