It's a good game. A little easier than wordle because you can go back and forth with variations on a few words by adding s and ed. Maybe a harder variant could be you go to the next level with a new set of letters still adding one more. Another variant could be you have to solve like a stack of them, so like you have 5 of these then to get to the next level all 5 have to progress, each with a different pool of letters.
