Nice endless runner! It's not bad as it is right now, but I think what could improve it slightly is to make sure when spawning a row of cows to not place a gap in the same place multiple times in a row, one time I had five rows of cows that had the same gap placement. Maybe allowing it to happen once is good so that the player feels lucky they got a freebie point but more than that feels kinda off.
Also, I played on PC so I don't know how it works on mobile, but it would be much better if the player was allowed to hold down the direction button to move instead of always having to tap it. When a gap shows up on the other end of the previous one, having to tap almost 10 times pretty fast can be a pain.
Good job on the submission, overall it looks like a solid endless runner! :)
