Plain physics changes everything in this game. I tried drawing lines to guide the plant.
Step click and draw with your mouse, use lines for the plant to follow.
Controls are click and drag to draw lines, and you can erase and reshape the landscape. The main goal is to collect all stars in each level, and the game runs in the browser.
Most important is to draw curves for better bounce, and think about where the plant will fall. Adjust lines slightly to make a big difference, and keep experimenting until the plant hits all stars.
