I walked my dog so long the seasons changed! Funny, simple game that's a good expression of the theme. The "pops" and little VFX when you ran into things were satisfying.
I think it would be cool if you expanded the idea in the future to include more elements. Like, this is just me throwing stuff out there, but I imagined if you could let the leash out or pull it in, and had to let the dog go farther out to pee periodically, haha.
In any case, nice job!
