Umm I think there are more requirements than just a thumbnail, and that thumbnail needs to be INSIDE the github project ---

something went very wrong with your PR, looks like you’re overwriting the entire targetconfig.json file with the code from your extension. take a look at the files tab of the PR i linked and @BLADEr’s PR to see what this should look like ---

@RizeUpDev a few notes: - please change the color of your blocks. add `//% color="#000000"` at the top of your namespace to set the block color (replacing 000000 with the color of your choice) - you need a LICENSE file in your repo with the MIT license text. If you’re using the makecode github integration, press the “Add a license” button to do this - the thumbnail needs to be checked into your repo and named icon.png. make sure “icon.png” is included in the files array of your pxt.json - you need to have created a tagged version of your extension. if you’re using the makecode github integration, click the “Create a release” button to do this - please add descriptions of each of your blocks to the README or in individual docs pages. see [this](https://makecode.com/extensions/github-docs) if you want to go the individual pages route - remove the tag in your extension, it’s not a sprite pack testing out your extension, i’m encountering a lot of bugs. right now coyote time doesn’t seem to do anything and if i register a slope it crashes the game once i overlap the slope tile ---
