Experience
Camera Module Observer
https://www.youtube.com/watch?v=2o38beaqPpUDirty Mind
https://www.youtube.com/watch?v=vpiG96PQL7QThe main character is your brain! You have to decide what to do by searching for words and creating a simple phrase which is the thing to do next. According to this action, points of happiness, food, energy, and time are changed. Some of those actions could be a little bit weird, and some memes will appear according to what happened. The objective is to keep the mind as happy and healthy as possible.
Within this game, I've created my own small game engine using only JavaScript and no other library where I implemented simpler collision, control, and engine update characteristics.
Geo Memo
https://www.youtube.com/watch?v=nusTmfqXhY4This game was awarded with a prize from the US's embassy in Bolivia through its cultural department. It also has given a lot of interest to the local press.
During development, I implemented my own camera smoothing control and recreated a huge part of Bolivia using Google maps through terrain-based tools of Unity3D.
Dawn of Robots
https://www.youtube.com/watch?v=2o38beaqPpUThis game is a 3D tower defense game in space stations, where you control the renegade robots and a central core IA. You have to avoid being disconnected by the humans.

https://www.youtube.com/watch?v=RJrtrDz8kdgIn this game, you have to survive through light sources and fireplaces, avoiding wild animals in the environment.
This project was implemented using navigation meshes and group selections. The characters were designed to mix typical "cholitas" of Bolivia and strange outer world characters.
