Cradle to Nowhere

The escape room is booked. The man who built it is still inside.

A first-person psychological horror escape game. A minibus brings you through the rain to an escape room booked for one player, but the man who built it has shut himself in, and he wants the game to go ahead. Room by room his puzzles lead you through a whole life, from the cradle on: a mirror over an iron bed, a wall of dark holes to reach into, old films of a childhood, a war and old age, a shaft full of mud, and questions you have to answer right.

Tools

Small apps that do one job well and then get out of your way.

Kanban Tasker: the home screen with the next To Do tasks, blocked tasks and upcoming appointments Kanban Tasker: the board's To Do column with due times

Browser · Android

Kanban Tasker

The task board that opens on what’s next.

Your next tasks in order of their due time, and only one task in progress at a time, so nothing is left half done. Repeating tasks never pile up: the next one appears only once the last is done. Blocked tasks stay in sight, and you can dictate a task with your voice, which your phone recognises itself and never sends anywhere.

The studio

A small studio with an unusual workshop

Silenos Works is an independent studio in the Czech Republic. We make games, apps and tools: things you play, things you learn with, and small utilities that do one job well.

The aim is the same for all of them: a clear idea at the heart, finished properly, and priced fairly. Much of it is free.
