interesting, I'll bring up the idea with my friend Budgeri, who worked on the game with me. If you intend on playing the game again, try using these secret cheat codes that are in the game:
if you hold the "z" key, and press 8, it will spawn additional enemies to fight (press the button more times to spawn more enemies)
if you hold the "z" key, and press 0 or 9, you can change the red vine to grow all the way or ungrow completely
