Altitude - A CMU Project
(Game Dev)

A two-week sprint to ship a 3–5 minute, physical-interface "skydiving" experience. I served as producer, playtest coordinator and sound designer, leading sprint planning, daily stand-ups, and a lightweight workflow in Google Space—intentionally skipping Jira to keep ramp time near zero.

Project Goal

Overview

MY ROLE:

  • Producer

  • Playtest Coordinator

  • Sound Designer

PT. 1   GAMEPLAY OVERVIEW

  • Prompted to design around “skydiving,” we built Altitude, a physical-interface game using two air mattresses, a stomach pillow, an Xbox Adaptive Controller (two hand buttons) and two foot pedals. The guest steers while “falling,” trying to pass through rings and land safely on the pad.

GOAL:

​Reach the landing pad; pass through as many rings as possible en route.

RESOURCES:

3 parachutes / 3 lives

DIFFICULTY CURVE:

  1. Above the clouds – green rings, large/easy.

  2. Inside the clouds (stormy) – yellow rings, smaller/moving; seagulls attempt to steal parachutes.

  3. Below the clouds – sunny but crowded with fast red rings and many seagulls.

PT. 2   MY PRODUCTION DECISIONS

AGILE, BUT LIGHTWEIGHT TOOLING:

  • 2-week scope and a team new to Jira → I kept overhead low with Google Sheets (backlog, owners, due dates, status) and one page of “definition of done” for each milestone.

Note-Taking Structure

PLAYTEST OPS:

  • I scheduled/hosted tests and converted issues into the Google Sheet with owners and priority / deadline.

  • I designed, built and updated the physical interface based on guest experiences.
