Tip: When determining a time limit, remember that players won't be as familiar with the level as you are. If you normally complete the level with around 100s left on the timer, others might run out of time on their first try.
First, you didn't upload a screenshot, again you just submitted the image that says you forgot to take a screenshot. Please stop doing that, and make a real screenshot instead.
But even worse, you stole the submission from someone else and just reuploaded it.
If you plan on getting your submissions here approved, then follow the rules. Uploading screenshots and not stealing other users work should be simple to understand.
