This is a really neat concept, I love the idea. Furiously swirling the mouse around to trap all the stuffed creations not only felt cool but tested my reflexes and quick planning. I was very confused at first because I didn't read the tutorial. I figured out how to thread only by accident. In terms of difficulty, I thought the dog was spawned to often and I was frequently getting overwhelmed. This was especially the case when dogs where coming to me in different directions. At that point, I couldn't move my mouse around that fast and precise to defend myself. Aside from those things that I think could be improved, I enjoyed the game :)
