Oh interesting, thank you for the feedback. I didn't consider making the blue orbs mathematically reachable, but that is definitely something I'll be looking into. As for the mold, it is kiiinda like an enemy! If you get caught inside of it as it grows, it'll wring the poor little slug guy out, and you'll be taking damage as it does. You can also slice through it with your sword!
Once again, I really appreciate the feedback!
