Here’s a polished, natural rewrite that fixes the mix-up between cat and sheep, improves flow, and keeps the cute game vibe:

Your goal is to help an adorable sheep collect every balloon in each level. Just tap the right platform at the perfect moment and let physics do the rest! Each level is cleverly designed to be completed in just a few moves, as the squishy sheep bounces playfully across platforms and gathers balloons in delightful and unexpected ways. Featuring smooth animations and a sweet, whimsical art style, Squishy Sheep will keep you engaged until you’ve collected every last balloon!

If you want it shorter / more energetic for a store page, just let me know.
