Title screen controls - Click "Start" button: Start the game. - Click "Load" button: Open a prompt that tells you to paste in a save code. When you do so and press Enter, you'll be able to choose any level from the first to the furthest unlocked one, and be able to use later plants in earlier levels if you want. - Z Key: View changelog. Game screen controls - Click on a card to buy a plant, as long as you have enough sun power. - Drag the plant to a grid square and let go of the mouse to place the plant. - Click the sun that is spawned either from the top of the screen (during Day levels), Sunflowers, or Sun-shrooms to collect it. - Click the green arrow button (or press Z) to speed the game up to double speed. If the game goes too fast for you in this state, click the arrow button or press Z again to slow it back down. - After completing Level 1-7 and unlocking the Chomper, you have to choose six types of plants to battle with before the level starts, since only six slots are available on the tray. More slots can be bought starting on the Night levels, when the shop is unlocked. - Click "Save" on the Level completion screen to generate a save code. You can then export it to a text file on your computer, and then copy and paste it into the "Load" prompt on the title screen if you want to continue from where you left off. Shop screen controls - Click an upgrade to buy it, as long as you have enough money. - Press space to return to the title screen.
