I've been toying with the idea of making a spiritual successor to this for years, always been too busy with work though. It's one of my favourite games of all time! Maybe there's some artists/developers here that would want to collaborate to reduce the time burden a bit? :P
I used to make my babysitter play while I watched, because I was astounded she could do so well on hard. Now I play on X-Treme and see if I can make it to the end.
Nowadays I load the game up once every few months and I tend to beat X-Treme first shot every time, unless I get unlucky with the toxic sharks. It seems you need around 110-120wpm and decent reaction times to finish it.
