Yeah, I remember that despite the trainer having infinite lives and using quick save points with VICE, the longplay was pretty nerve-wracking, especially at some platforms where you had to jump to another with pixel perfection . But I don't give up that easily. 😉 I will be happy to look at the current version and possibly show it once again in one of our next liveshows.
