Fantastic game, absolutely great. The challenges are a bit simple though, every single one practically says use only 2 plants. maybe add some challenges with beat under a certain time, or win after a cetain amount of time (the latter would make the crystal spawn rate insane) you could add different color crystals just for fun too.
LOVE THIS GAME
word for improvement, i like the look of some of the enemy buildings and ships better than my own, you should allow players to pick their color and their race. Other than that its fantastic.
