ABYSM - Dive the Deep Sea
A capable developer can reproduce the core descent, audio, and local unlock in a few weeks, but matching the original app's proprietary art, audio, translations, App Store presence, and polish is nontrivial—keeping the paid product is reasonable if that full experience matters.

Not priced
No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

No published price to break even against.
No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Descend through depth zones, observe procedurally generated ambient audio and pixel-art creatures, and unlock deeper zones via a one-time in-app purchase.
What it still won’t have
- Original pixel art and visual polish (© Apoorv Darshan)
- Proprietary procedurally generated ambient audio and its tuned mixes
- App Store listing history, ratings, and discovered audience
- Included translations (16 languages) and existing localization work
- Developer goodwill, name, and copyright-covered content
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
ABYSM - Dive the Deep Sea does not publish a price we could read, so there is nothing to compare against. What building costs is below.

Runnable build prompt
Build a single-player iOS app in Swift + SpriteKit (or SwiftUI+SpriteKit) that recreates a minimal ABYSM experience: implement vertical scroll/descend of a procedurally populated 2D scene, show depth-based creature/landmark cards, play procedurally varied ambient audio loops per zone, persist dive position and unlock state locally, integrate a one-time non-consumable in-app purchase via StoreKit (include restore), support basic controller input and haptics, and ship with one language. Out of scope: reproducing the original art assets, multi-language localization beyond one language, analytics, server-side components, and social features. Include error handling, unit/UI tests for purchase and persistence flows, and a simple CI build for TestFlight.
How we checked
How the score was reached
- Partly verdict base52
- Evidence score52
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
