First thing I noticed was how polished it is. The mood is perfect, the atmosphere and environment is beautiful and kinda creepy. It's soooo cool to see voice acting in a jam game, this is only the second time I've seen it, and it sounded totally professional. The music is a perfect fit, very sci fi but also very "oh no!" And any time I see 3d in a jam I'm automatically impressed. The fact that you made your own models is even more impressive, they look perfect for the style of game.
The whole concept is cool, and winding through the tunnels feels reallllly satisfying, it's a great mechanic. Unfortunately I keep dying just before detonating the third core. I must be making some really dumb mistake, but the enemies overwhelm me at that point. That's nothing against the game, just me being garbage at it.
It's a super strong game over all, wonderful job, everybody!
