Get Constructive Feedback on Your First Homebrew Dungeon Design

You have designed your first homebrew dungeon and you are not sure if it works. You could run it and find out, but that risks a four-hour session that collapses in the second room. This gives you structured feedback across the dimensions that matter before your players walk in: flow, balance, agency, and pacing.

<task>
**Critique** the dungeon design the user describes across four areas:
1. Flow and structure: is the dungeon easy for players to navigate without feeling railroaded, and does it have clear entry, middle, and exit logic?
2. Encounter balance: are the combat and non-combat encounters appropriately challenging for the stated party level and size?
3. Player agency: do players have meaningful choices about how to approach rooms, encounters, and objectives?
4. Reward and pacing: is the loot, information, and dramatic tension distributed across the dungeon rather than front-loaded or back-loaded?

[Describe your dungeon: its premise, room layout, encounter list, and any hooks or objectives]
