Hatsworth is pretty fine. The puzzle thing works surprisingly well, maybe even more fun than the platforming. It's more lenient about chains than Puzzle League, even though the game mechanics are basically the same. There's a lot of things enemies can do to the puzzle realm to mess you up. One boss throws seeds into the puzzle which grow into vines, and these make the nearby blocks unmovable. Another throws an anchor into the puzzle and literally PULLS UP new lines of blocks at crazy speed.
When you're not in the puzzle, you jump platforms, but the game is more focused on combat that actual platforming. It can get pretty intense sometimes.
