Fell & Sell Demo Rewards & Full-Game Differences
What the demo proved, what changed before release, and the special furniture reward fixed in Ver. 1.0.1.

The demo is useful for learning the basic dungeon-to-shop loop, but it is not a safe source for exact full-release balance.
Demo 2.0 changed major systems shortly before launch: performance, destructible dungeon objects, customer traffic, Comfort, crafting costs, material prices, controls and tutorial behavior. The full version then added deeper dungeon biomes, new enemies, larger bosses, more items and shop upgrades.
Special furniture reward
Players who participated in the demo were promised a special furniture reward. Ver. 1.0.1 fixed cases where that reward did not appear correctly in the full game inventory.
If you qualify and do not see it, make sure the game is fully updated before assuming the reward is gone.

Demo saves and old footage
Use demo videos to learn visual systems and general interaction patterns, not as authoritative price/recipe tables. Balance-sensitive facts such as prices, crafting costs, furniture stacking and dungeon behavior were changed repeatedly right before launch.
