It's an OK prototype. Apparently it was made for a game jam. Though I have to say it was very confusing at first. There are no instructions, and plants transmitting and storing data is not a very intuitive theme.

At first I didn't understand what the seeds were for, what each level of each plant would give if I leveled them up (the sprites are the same), why they were all producing 8MB/s, when or why a plant would become "bricked", or if it’s possible to recover them from that state (I couldn't figure out how).

Also, is the gameplay supposed to be going from plant to plant and clearing the cache? Did I understand that correctly?

It's a very early prototype and it doesn't even have autosave or help, but I still recommend checking it out for a couple of minutes.
