I remember, as a student in high school, seeing this event get barely a paragraph in our textbooks, and it made me so angry. My mother was there on that day; she was friends with three of the four people who died. She was passing by on the way to class, and a friend pushed her down and told her to run when the shooting started. On a different day, she was chased back to her dorm by guardsmen with tear gas for walking with a group of three people, who nonetheless fired it directly into the dorm after she and the other students had made it in. She had to transfer away from Kent State due to the trauma of everything, and she has struggled some degree of PTSD ever since.
Semi off-topic (?), but I'm a developer and researcher working on moving into game audio and composition. This may or may not be amenable to solo devs (depending on where you feel game resources fall), but I'm looking for games to produce audio/music for so I can gain more experience! Some composition examples are on my SoundCloud: https://soundcloud.com/superlumic. Can also provide some small demos including actual gameplay.
Also, for non-solo folks, I have some game programming experience and am comfortable implementing audio [or figuring it out on platforms I haven't used] and would be happy to chat about possible collaborations. :) Email in profile.
Thanks for reminding me what day it was today.
