Interesting thumbnail which lead me here. I liked the very relaxing music and tone, also the sound effects are a good fit. I enyojed trying to find new combinations and the exploration effect when new tile types were created by placing water nearby etc.
Really cool concept.
Could need a little bit of polish. I finished the game and the end screen shows my score but i have to reload the game to play another round? Please give the player the option to restart. (Probably you ran out of time there)
Very nice! Thanks for creating this!
