Just click the green flag, sit back, relax and have fun! (at least for a singular minute) Countdown will flash between white and red when the minute is up - additional notice for the last 10 seconds is provided by the colour-coded circles that start displaying when timer screen backdrop becomes orange and will gradually build up until the end. Based on the remaining time, the screen itself is also colour-coded. Enjoy! ;-)
Emphasised the '23' to signify the year I made this project in - (29th March) 2023!
