It's a classic electronic stopwatch. You know how to use it. START to start, STOP to stop, & RESTART to restart. Can be used for stuff like speed running. Challenge: Speed-Run Undertale: Shattered Light and post your time in the comments section. https://scratch.mit.edu/projects/990220799/ NOTE: It is not going to count days. I will not be adding a days value for obvious reasons.
Have fun with it! :)
