Nonono, you've got it wrong. I think the stress IS supposed to be part of the experience, but not the frustration. Also, as another commenter suggested, I think I'm going to replace the limit with a score system so that I can get the most possible stress with the least possible frustration.
I would have loved to make a little introductory tutorial (as well as a volume slider) but I couldn't.. I tried kinda replacing it with a very easy, "I teach you the mechanics" kinda level, with X > 0, and 0 is 7. Hope you liked it nontheless! One of the main goals was to have an original take on the theme, sooo.. I can say I'm happy!
