The game is a downloadable Windows PC survival simulator. The Steam demo is free and includes five cave layers with the current features and mechanics described on its store page. The itch.io page offers the prototype as a name-your-own-price download. Neither official source advertises an HTML5 browser build.
Which version should I choose?
For the current demo, use Steam. The itch.io prototype is another developer-run download route; its files and features may differ. Check each source page for the latest build details before following a guide.
Can I play in a browser or on a phone?
No verified official browser version is linked from the supplied Steam or itch.io pages. This site reserves a game frame for a future authorized web build, but currently directs you to official PC downloads. Steam lists Windows 10 as the minimum operating system for the demo.
What about the full release?
The full PC game launched on 9 November 2026. Its official Steam listing describes eleven layers and three playable characters. The free demo remains a separate five-layer download, so check which edition a guide or mod targets.
Official descriptions: Steam demo and Orsoniks on itch.io. Where this page gives a recommended order, it is a general survival strategy, not an official rule or verified item recipe.
