Really solid concept. Some frustration came up from the level design, hide and seek, and lack of freedom to, y'know, not murder my five closest comrades.
Of all the areas to improve - as a shooter, as a game of hide and seek, as science fiction - I would like to see more lore. The orb, the station, and the crewmates all felt flat. It's fully playable in 30 min or less as you learn the station. That is, admittedly, probably too long for the amount of real content.
But, good work putting all this together in one week, it is a compelling experience. No glitches, fast and nostalgic movement, cosmic horror. Glory to mankind.
