Edit: I saw he updated and added some screenshots from his levels. Now, I'm happy.
Edit2: Apparently, people don't read anything other than the title then just click the links and reply. Summary: There was a guy put the template on greenlight without changing anything. He saw he may pass the greenlight with a template then he made levels and updated his screenshots and video. When people write comments about this, he said, he bought the sprite pack (it's not a sprite pack, it has mechanics.). Also, in IndieDB, he said he made the game with a custom engine (it's not a custom engine though, it's Construct 2)
