Thank for playing! What did you find wonky about using E? Is there another key you would have preferred to use? Thank you for the feedback!
Ah sorry for the confusion! The key itself is perfect. Its how there seems to be a delay between when you press the button and when the plant grows and that straying from the plant in this timeframe cancles the process. (which was a more common issue on the platform stalks than the bouncy vines weirdly enough)
