From briefly playing this I found that the gameplay is similar to the original Mario Bros and it overall was pretty interesting.
I think that the use of the crank is pretty good. I only wish that there was an animation for the digging. I think that the sound for digging is pretty good and is a good indicator.
I think the barking is pretty good and I was happy to see that it was easily usable while jumping.
I think that the How to Play was really useful to have and I am very happy that this was included. I was kinda hoping there might have been an easter egg when you clicked through the tutorial enough times but without one it's totally fine.
Overall the game is really well polished and I could see myself playing more of this from time to time.
