Eight levels. Not backdrops — arguments.

You've flown through eight levels. Most shmups use environments as backdrops — the thing behind the bullets. We didn't do that. Each of these eight locations was designed to mean something. Here's what they are.

Remove the Sentinel. Remove the enemies. Remove the bullets.

What's left?

A world. And that world should feel real whether anyone is fighting in it or not.

That was the design test for every environment in *Interstellar Sentinel*. Not "does this look good behind the bullets" — does this look like a place that existed before the Sentinel arrived and will exist after they leave?

The Lovecraftian influence is most visible here, not in character design. These are places that feel like they're being *remembered*, not just seen. The progression across the eight levels isn't just mechanical difficulty ramp — it's the world getting more wrong. Level 1 is a universe under pressure. Level 8 is a universe that's been breaking for a long time.

Three people built these. Eight locations, fully realized, visually coherent. Each one a different answer to the question: what does crisis look like at this scale?

Reviews mention the weapon system. Reviews mention the Chris Huelsbeck soundtrack. The environment design is quieter — but it's the backbone of why the game feels like it's happening somewhere real, not just somewhere rendered.

The art book preserves this work. It's documentation before the game compresses it into a background.

*Thursday: the other side of the conflict. The antagonist — and why we gave the enemy the same visual treatment as the hero.*
