This is really very poor; a simple idea with potential, but executed exceptionally badly.
My first (and, ultimately, most minor) annoyance was that not all of the pieces cycle through their different orientations in rotational sequence. For example, some of them might turn to 60°, then 120°, then flap over for no reason to 240°, then back to 180°, then to 300°... Obviously, this isn't a deal-breaker, but it certainly is indicative of the level of care and attention put into the game, and into making your interactions feel at all satisfying.
The next annoyance was the soundtrack - which would be inoffensive enough, were it not on such a short loop. It quickly becomes maddening, and I'd be amazed if anyone would choose to play for longer than 30 minutes without muting the music and listening to their own choice of background audio instead.
Thirdly, and Infinitely worse: some of the rotational orientations are simply not available. Based on the attention to detail displayed in other areas, this may well be because the developer just overlooked them. On the other hand, it may have been an intentional choice, with the aim of increasing the difficulty of the game. If so - what a staggeringly arbitrary, inelegant, artificial means to do so. Again and again, you will find yourself hugely frustrated at being unable to use a piece as you actually want to, for no good reason. If unintentional, it is profoundly incompetent - if intentional, it is just profoundly stupid.
Another kick in the teeth is the lack of any function to save your progress. You can either keep playing indefinitely for however long it takes until the RNG and missing orientations screw you over, or you can quit and have to start from scratch next time round. If you ever decide to come back, that is...
Because finally, and the real nail in the coffin - if you can get beyond all the issues described above, as soon as you are working up a half decent score, the game starts to slow down and become less responsive, eventually to an unbearable degree. There is simply no excuse for this - I can't imagine how ugly the coding must be, for such a visually and mechanically simplistic game to behave in this way.
Definitely not recommended, and hard to imagine how anything else by this dev could be worth your time or money.
