donutGoku’s game had a core problem: it wasn’t actually a game. Players can evolve a lot of flowers & do it in a controlled way, but you had no reason to do so.
So how do you make a game out of a flower growing toy? You prompt the player to grow a specific flower, using a cheekily branded Sony monitor. Each session begins with a single flower on the screen — players need to drop the appropriate flower into the foreboding flower consuming device below the screen. As long as you do it before your screen is completely overtaken by flowers, you win.
