Removed a star for being able to make the game unwinnable (Spoiler - click to show)by launching every ball through the window. Removed another star because I had to guess-the-noun and at the end had to try (Spoiler - click to show)aiming the machine at every single parseable noun to figure out how to (Spoiler - click to show)get the acorns from the tree.
Otherwise: short, well described, and whimsical.
