Interesting idea and overall art style is appealing. Direct help/info, which fields fit well together would be helpful (some sort of colored indication maybe?). Game-play feels a bit slow, maybe reducing the map size could help. Add some subtle "juicy" effects like sounds, music, (particle) effects to spice things up. :)
Feels better now, definitely. Especially having some sort of particles and sound effects adds a nice touch. Music is a bit loud though (thanks for adding a volume slider).
Ultimately seems like I forgot/misunderstood some rules. When placing/accepting tiles, the impact on score is not obvious. :S
In total a big step forward, well done!
