SGI machines always felt almost like mythical artefacts, back in the day, so it's very cool to see it as platform for retro gamedev.
I honestly can't play 6DoF shooters for long - I always dug the concept, but they just break my brain. (It always made me sad that I couldn't deathmatch in Descent with buddies who were into it at the time). But I managed to peek at this long enough to appreciate the accomplishment. And the neon visuals feel like they really capture the SGI aesthetic. So congratulations on a game that made me disoriented, nauseated and happy all at the same time :)
