Description:

A rollercoaster-esque mine experience game where you use a flashlight to dissipate evil spirits who are trying to stop your cart from making it to the end. This experience was developed In the CAVE, a location based experience where the game is projected onto screen walls around the viewer. This CAVE also includes a moving floor platform and theatrical lighting options. I, along with nine other individuals, designed the game for CMU ETC's Building Virtual World's course, specifically for the ETC Fall Festival 2021. For the livestream, we used one guest as to not block the entire view, however, the experience can actually have two players at a time, with room for one more person to experience it at a time if they do not wish to interact with the scene and kill spirits.

Duties and Personal Contributions:

Designed and implemented the Ghosts
Designed and implemented the flashlight attacks
Designed and implemented the puppeteering system run by the host
Worked with sound design to incorporate the music and SFX.

Process

The Red Spirits

This project was designed to be a mix of two team's initial projects in order to be presented at festival. As such, we did not have time to incorporate any new and elaborate mechanics, so I designed and implemented the red spirits, based off of the use of Clementine, the friendly spirit orb, that was used in one of the base projects.

We first had ominous red orbs floating around that would be dispersed with the wave of a flashlight, but they were not noticeable enough, so the orbs were changed into actual specters.

I also added a vfx particle effect when they blew up to make it look more like the light made them disperse, rather than they just disappeared.

The Giant Spirit

One thing that the team agreed on was that we wanted a moment at the end that had a higher amount of intensity than just hitting a bunch of tiny spirits that are floating in the way.

Thus, I designed the giant ghost. Both guests have to continuously slash it with light in order to kill it in a large cacophony of death.

Several changes were made at date after our trailer was produced that allowed guests to see that they were doing damage and the giant spirit would slowly encroach upon the guest the longer they took to defeat it.
