Hi, you asked how I would improve it. In this remix I think I have made the code simpler (in the three sprites named kriblo). I deactivated your sprites in this remix. I also added a zero hour costume. The second delimiter is on the backdrop (I felt it was easiest). Hope this helps.
Original instructions: This project took two days to complete, it shows a working clock. The clock might not be the right time if your device has the wrong time, the clock shows the same time as your device's clock is set. It can also show military time/24 hour clock if your device has military time/24 hour clock. Bug fixed! when minute = 0, there was no "00" costume so it would stay as "59" until it was "01"!! You can backpack my hour sprite and my minute sprite as long as you give me credit for it :) Make sure to ♡ and ☆!
