Ok this project took us two weeks. The original story and idea is made by Facundo Balboa (MonoFlauta in Newgrounds) he also is the programmer, the artist Is Huw Millward (Neverzonegaming in Newgroudns) and voices by Fro (Newgrounds account).
This story is about a yak called Rigoberto that travels to find something... it's a difficult game, but not an impossible one.
You only need arrow keys, the bosses will defeat their selves so you don't need to attack, good luck to everyone :D
