A very clever little game with a super off-the-wall concept. The random boards grant a huge level of replayability. Very cool music, and great "game juice" overall.
Some suggestions for future improvements:
-I felt that 20 turns was too long. Shorter matches of 5-10 turns might be more fun, then the player can switch to a different seed.
-The character of the game does not change as the turns wear on. The endgame should have a different feel than the early game.
-The rocks did not seem to do anything. I think it would be interesting if they had a function.
