I like the game Said! Good job with the idea, and the pixel art is nice.
It felt repetitive after sometime but you can add some day-night cycle or some variations to make it more challenging, since for example you can buy watermelon (which has the best rate of return) which is cheap and available from the start, then extending the space and keep doing that forever, but with some nice animation and adding more obstacles and design element that will give you an even more awesome game. Keep it up!
