Choose the correct product and store
On a narrow screen, scroll the table sideways to read all columns.
| Your device | Full game | Opening preview |
|---|---|---|
| Windows or macOS | Steam premium game (opens in a new tab) or Rusty Lake’s itch.io page (opens in a new tab) | Use Download Demo on Steam (opens in a new tab), or select the demo on itch.io (opens in a new tab). |
| Android | Google Play premium game (opens in a new tab) | Google Play Lite (opens in a new tab) — a separate listing. |
| iPhone or iPad | Follow the iOS store link from the official game website (opens in a new tab). | Find the iOS preview through that same official website; check the listing available in your region. |
The official game site is run for Rusty Lake’s product. This companion site provides reading help and does not sell a copy of the game. Check the publisher, product title and premium/Lite label on the destination store before paying.
Install from the store you selected
- Steam: choose the premium purchase or Download Demo on the product page. Open the resulting entry in your Steam Library, install it and use Play after the download finishes. Check which entry you launched if your game stops after the opening.
- itch.io: choose the paid game or the explicitly labelled demo, then the download for your operating system. Follow that download’s supplied instructions; the existence of a download does not mean the game runs in a browser.
- Android: open the premium or Lite Google Play listing above with the account and device you will use. Let Google Play determine device availability and complete its installation.
- iPhone/iPad: follow the official site to the regional App Store. Check the listing’s required iOS/iPadOS version and supported devices there, then use the store’s purchase/install control.
A unavailable listing or a device marked incompatible is a store/compatibility issue. A successfully installed game that closes on launch belongs to the not-starting guide. Keep the store receipt if you need purchase support.
Check compatibility before purchasing
On a narrow screen, scroll the table sideways to read all columns.
| Requirement | Windows | macOS |
|---|---|---|
| Operating system | Windows 10 or later | macOS Big Sur or later |
| Processor | 2.4 GHz dual core | 2.4 GHz dual core |
| Memory | 4 GB RAM | 2 GB RAM |
| Available storage | 1 GB | 1 GB |
The Steam macOS text includes an inconsistent numeric version label; Big Sur is the named operating system used here. These are minimum store requirements, not a test result for your machine.
Need a 32-bit download? The checked official requirements do not establish that a supported 32-bit game build exists. An operating-system name alone does not prove CPU architecture compatibility. Ask Rusty Lake support (opens in a new tab) with your exact Windows version, architecture and intended store before purchasing for an older system. Do not infer 32-bit support from an unofficial installer filename.
Mobile operating-system and device requirements belong to the specific premium or Lite listing. They can differ from the desktop requirements above.
What a download link actually gives you
An official downloadable desktop package can be the paid product or a separately labelled demo. On mobile, Servant of the Lake Lite identifies the preview; it is not a way to unlock the premium story for free. An APK or IPA from an unidentified mirror does not establish its publisher, version, purchase entitlement or compatibility.
After installing, use the premium walkthrough for the complete weekend, or the Lite/demo walkthrough when your opening matches the documented preview. Store pricing and discounts are shown by the store for your region; no fixed worldwide price is assumed here.
