I loved this game, fun world to explore with varied puzzle goals and a great aesthetic. I don't actually know exactly how I solved the last puzzle (the two compasess; I'd gotten all the numbers to light up and I was near the large bolder, tabbed over to write some more here, and tabbed back and it had moved), but otherwise I finished with all the carrots.
As others have said, the invisible walls were a little bit frustrating (more because there are some areas where nothing is on the horizon and I can't get a sense of whether or not I'm even moving anymore). Making them visible would have worked but having a bit of texture on the ground that changes as you move would have also solved it.
I was jonsing for some additional reward when I got items, even a simple bfxr coin beep would have been nice :)
