I love the idea but there is not enough of an incentive for the player to go for the zoomies, I was able to just go around killing all the squirrels maybe down the line where there are too many it might be useful. But if the main game mechanic is looping to catch the tail then maybe give more reasons to the player to do that. Otherwise love the cute vibe, pixel art is clean, the grid helps as well with the movement, and the sounds are good too.
