Really nice, even though I am not the biggest puzzle game enjoyer :D The art and progressive music are great.
One thing I would suggest adding in the future is a bit of tutorialization at the start. Also at first I was not very sure what can be clicked and what not, but figured it out after some time... maybe some more obvious highlighting of what can be selected would be nice? (but also did not read the description first, bit of a thing I try to see how far I can get without help xD)
But overall really solid, good job :D
