This is a nice concept with great visuals and sound!
It took me a while to work out what to do. Perhaps it needs to be more obvious what the first things the player should do are (e.g., buy plant pot and seeds).
It would also be nice to be able to see how much money you have and what you can afford in the purchase menu.
I did encounter quite a lot of bugs, but once I worked it out the gameplay was solid and I managed to unlock two upgrades. Great job!
