I uploaded a tool called SpriteSheetProcessor and wanted to submit it to the game jam because I heard you can keep working on your submissions afterwards too. However, it wants me to upload a game? Should I re-upload my tool with the Games tag?

Is it preventing you from uploading?

If not, the submission box asking for a "game" is just the default noun used by Itch.io, just ignore it and upload the tool as usual...

Sorry, I'm not used to the site yet. It did submit the game after all, I just wasn't looking properly. Oops!
