Great concept.
If I was to share one criticism, it is that I find the tiles a tad confusing. It’s easy to mistake either a locked tile or the glow light thingies for something interactive and waste a move or two. Other than that, well done.
Yeah, I was thinking about this issue for a while now, and currently I'm trying to make all the sprites easier to read quickly while keeping stylized look. Thank you for your comment, I really apreciate it :)
