Decent game. Little bit repetitive, the easy levels went on too long for me, a few for a tutorial then move on. Skipped forward, the medium levels felt like a better difficulty for the start.
Once comfortable I tried some of the hard levels. Again a bit repetitive for my taste, but there will be some who adore it. The hard levels jumped between I got the star in one go and I had to stare at it to find any solution, let alone the fewest moves.
I think the fewest moves is a good extra challenge for people who like optimizing. But thats not me. I personally was surprised by the final position of rotations often. I don't know what was off but it felt like I couldn't predict them correctly.
Suggestion:
play with different amount of moves and cuts. 4 cuts but only 3 moves so you have to have to have 2 disconnected peices stay still or 3 cuts but 4 moves so all four peices move.
Overall really solid game, can be improved but a great base
