Haven't played it yet, but from what I know my impression was that this game was as much a test bed for his new programming language as it is an artistic expression. I wouldn't be surprised if some puzzles made it in because they were a good test of some novel comp time feature (i.e. the real puzzle game was making the language, not playing the game).

And I bought it day one without reading reviews. Whether or not the game is good, personally I'm happy to support someone who's completely self-funded working on PL design. Not that many people are in position to do that kind of work, and even fewer with a documented history of finishing things.
