Happy to see interest on this ! In Puzzle, (for example: Pa1_daishizen.arc), open any tileset you want to replace, after click on "Import image". Use the images there are in the main post (on the top). Puzzle will import it and assign automatically all the behaviors :
After, save and use this tileset file (.arc) in Reggie Level Editor and create your levels. Don't hesitate to tell me if you encounter problems.
And please share levels you created here so we can play them also !
