That game really reminds of the art style of the daily deal game: AER – Memories of Old.

Oh and here's a Google translated version of the review by Ronsn (originally in German):

In Mulaka, you play a warrior, a shaman who, with the support of nature and the supernatural, as well as fine Hack & Slay or other movies such as javelin throwing or firebombs, goes on a journey to rid the world of evil ... ... does not seem profound , typical Äktschn. The story, however, is profound, inspired by the long-distance runner-known North American Indigenous Tarahumara people, and has much knowledge of what one likes to absorb. The game is without sync voices, the text is clear and not too much, the cutscenes are very beautiful pictures and story in text.
The gameplay is good, but not top: the camera must always be set manually, which does not always work in hectic situations. The character remains in completed combos in a short, millisecond-long rigidity, which often has an opponent hit, if more than two opponents encircle one. The encounter of flying opponents with the spear proves to be difficult. The genre is noticeable to Mulaka but still good, you're fast in it, especially as a genre fan, and it's fun to give the opponents free neck beats. The bossfights are fun, sometimes demanding, but later also like hectic.
Overall, I recommend Mulaka: for fans of indie hack & slay, action-packed action adventurers and action fans who like Story. 10% of the proceeds go to the Taramuhara community as a donation, I think a jutte thing.
