The music and graphics fit together nicely, along with the game's premise. Maybe I'm not very skilled at playing these types of games, but I found it difficult to know if I was actually harvesting the plants or not by pressing 'E'. Might be neat for user feedback if harvested plants would slide off to the side in a grid of empty cells, or into a storage bin, and then the user would know how many plants of each type remain as a requirement to progress through the level successfully. Also, maybe watering the plants could prevent them from dehydration instead of making them grow faster than otherwise. In any case, it is an enjoyable game with nice music and sound effects, good job making this!
