Hello, I'm Daniel Case. I wanted to let you know that one or more of your recent contributions to Space Invaders have been [ disallowed by an edit filter] as they did not appear constructive. If you only meant to make test edits, please use the sandbox for that. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page. If you believe the edit filter disallowance was a false positive, please report it here. Feel free to ask for assistance at the Teahouse whenever you like. Thank you. 20:35, 14 October 2022 (UTC)
