Together with Natalia Lany, Natalia Wydra and Pawel Bród we made this small JavaScript game from screatch for the js13kgames.com competition (2014 edition).
You can check it out here: http://kdzwinel.github.io/TheMoleGame/
Code is modular and you can easily make similar games based on our work.
We've got 12th place in mobile category and 33rd in the desktop category (out of 129 entries!).
danielmahon for creating the panda character that our mole is based on.
