Is it me or is the mole kind of cute? It is a fun idea and I like the puzzle concept of co-ordinating actions between the man and the mole at the same time to solve the puzzles. Nice use of a little bit of danger in the last stage to keep the player on their toes! I wonder what other ideas you could use - maybe in some stages the man could have an ability that the mole has to rely on to progress! Nice job!
