Really well made game! Loved it so much, made my friend download it so he can play the puzzles! I love puzzle games and this scratches the right itch for me personally! Art is also amazing. One change I would like to see is to instead of resetting the level have like a 'reset, past turn', so I could try my strategy from a different angle without needing to redo my idea of solving the puzzle from memory. Also to note, the game didn't load properly 2 times when my friend was trying to launch it, though worked the third time. Perhaps it's his hardware? I couldn't really tell.
I also would like to see different twists if you decide to further polish the game! Keep up the amazing work :)
