I love my pond too. (I SWEAR I remember putting a rating on this one but it turns out I didn't???)
Very cute game and I like the grapple hook mechanic here! I had to take a bit to get used to the fact that left/right meant you threw your hook up-leftwards/up-rightwards instead of straight left/right, that Celeste Classic 2 influence really be screwing me sometimes. But it was otherwise quite pleasant to play! I think you can make a full-fledged metroidvania with this if you add some non-linear exploration and upgrades.
