Well, I'm not a judge but here's some feedback.
I laughed way too many times when I cronched into rocks, especially the first time because it was a surprise. The sound design (overall) was really good. I assume it's stock stuff (you should have asked me to join - I could have made some audio just for fun!) but it's still well chosen and really works with the comedy.
I like how the speed increase changes your ability to control the leash, which introduces subtle changes to the gameplay, although on the last upgrade it also makes it a harder to get through doors and align with upgrade terminals to read/upgrade. I thought the upgrade path was pretty well balanced to keep it interesting and also not drift into a grind. I don't know where you go from here, though, to make a larger game.
Thematically it would have made sense for me that the edge of the forest/property had a fence or something (rivers? mountain/rocks? thick underbrush?). I always find it weird when you can just run off into infinity.
I couldn't find a way back to the start after "To Be Continued..."
Thank you for having arrow controls as well.
I saw at least one typo. (I was trying not to look too hard but, you know...)
Overall I really enjoyed the humour and I liked that it was easy enough (so no sense of frustration) but also fun and balanced.
