It seems like you went with the strategy of making a very unique product - in terms of art, music, and design and it works! Its nice to see a turn based / grid based game like this in a game jam, its the first one I've seen in any game jams.
As others have pointed out, due to the nature of the core mechanics and design, getting through a level can be slow, but I feel like those who really like this genre of game will appreciate this. I like how you introduce concepts to twist the main mechanic as the game goes on.
