Double post of the same project because I enjoyed this concept. In this project, there are tests for Mobile/Pc and Turbo Mode. Mobile/Pc Test: A very neat idea that probably was done before :| The gist of it: mobile has some alignment issues and text display quirks, and we've utilized that with a piece of text that aligns to the center for PC and aligns to the left for mobile. We then use a color detector to detect a single piece of text (for example, a period) on the right side which isn't that far right on mobile, and the output of the touching statement is equal to mobile (no) or pc(yep). Note: this can't be tricked, because there's no user input involved, which I like. Also, because Scratch is quirky, the quickest time that I've found works for this is 0.85 seconds. Turbo Mode Test: A generic FPS test. Nothing really exciting about this, just timer-based.
