This was a mobile game, inspired in Lemmings, that we developed in Unity 2D using tiles within the framework of a collaboration with the Ukhupacha project, which is responsible for climbing, caving or diving in areas of difficult access, to obtain material of scientific interest, as well as some of its affiliated brands such as Petzl, a company specialized in the manufacture of equipment for mountain sports. In this project I was in charge of the gameplay programming, the implementation of the interfaces and part of the level design. Although it was an unpaid partnership, it gave us a highly satisfactory first experience with the working world of video games and also a positive contact with serious games after having been initiated in the subject with Liesure.
