Very fun game!
Love how it fits the jam theme with the needs of each block.
Each block's little dialogue bubble is great and the relationships in some levels were very well executed. I especially liked the "everybody loves Sana" level.
One issue I had was that the block requirements couldn't be checked after placing them, so I had to remove them a couple of times until I memorized the requirement, which may or may not have been the intended gameplay experience.
I enjoyed playing this game and clearing it! :D
