The way this works is by checking the X position of a sprite that draws a bar made from the pen extension, showing visually how well the device you are using works. This bar also detects Turbo Mode. It may be inaccurate by a bit, because my device is a little low on performance. To help improve this, please comment your device performance response and maybe your average computer performance at most.
This project was made in under 100 blocks, and this was just a little side project to test my coding skills. The time left for detecting device performance may be inaccurate or broken on the first play.
