About This Demo

[h1]Free demo — play the Shallows[/h1]

TideWane is a deep-sea idle dungeon crawler. You pilot a submersible, harpoon fish for PSI, upgrade your drill, and slowly dig deeper.

This free demo includes everything in the first zone:

[list]

[*] 10 Shallows fish species with unique behaviors (fast darts, armored puffers, stealth hunters)

[*] 5 milestone bosses at increasing depths

[*] The full 108-node PSI upgrade tree

[*] One Ascension prestige layer — your first taste of the meta-game

[*] Artifact Forge with visible pity system (no hidden drop-rate tricks)

[*] Full Bestiary + Zone Shop for the Shallows

[/list]

[h2]What's not in the demo[/h2]

The demo is content-limited to Zone 1. The full game adds four more zones (Kelp Forest, Twilight, Abyss, Vents), 20 more milestone bosses, the Transcend prestige layer, the permanent Void Tree, and the Deep Dive endgame.

[h2]About your saves[/h2]

Demo progress stays in its own save slot. The full game starts fresh — this is deliberate, because the full game's economy curve differs from the demo's and mixing them would break early balance.

[h2]About the developer[/h2]

TideWane is my first solo game, shipped April 2026. Feedback is welcome in the Community Hub — most of the patches after launch have come from player suggestions.
