At least, he isn't making games anymore on this site. Look, his last game here was Multimove, and he never did any other games here after. Then look at Poki, he did other games there that aren't here. So he apparently is now doing games on other sites, and not publishing them anymore on Itch.io. He was also on Newgrounds, and he also isn't publishing his game there anymore. So, yes, you can only play his new games on Poki, but I found those games on other sites, such as y8, but I only found Jumping Shell there. Also, rest in peace those menu screens (those screens you see before going to the level select), we'll always remember you, were last seen in One Button Bounce.
