Solid and uneasy atmosphere, nice exploration vibes, though walking through the tunnels could be made smoother without having to duck or jump every half second. Enemies were dull in combat yet interesting in exposition, "health bar" was a nice touch, and the frequent yet brief relays between the player and the unknown "operator" really helped add to the creepy tone. Definitely flipped a bit when the friendly NPCs first showed up, as it gave me serious SA-X (Metroid Fusion antagonist, a game which this one reminds me well of) vibes. Overall great stuff, would love to see it expanded upon.
