Description by Syndicates BOO Studio Written by the developer, not by AppBrain. Click to read.
Harrow Bay, Massachusetts. October 1972.

A man is found at the scene of a murder with blood on his hands and no memory of the night. He says he was asleep. The town says he is a killer. You are the young lawyer who has taken his case.

The Sleepwalker is a dark murder mystery and courtroom drama, told through your own casebook: ink-and-wash drawings, taped evidence, a red-string board and a map of a fishing town that is hiding something.

INVESTIGATE
Do the detective work yourself. Visit the pier, the church, the institute on the hill and the houses on Second Street. Question witnesses, collect exhibits and pin every lead to your board.

GO TO TRIAL
Cross-examine, object, and present evidence at the moment it matters. A single wrong question can lose a juror. A single right one can break a witness.

CHOOSE
Your decisions shape the case. Take the plea or fight. Trust your client or doubt him. Protect a witness or expose her. Sixteen different endings wait at the end of the trial, and not all of them are verdicts.

LISTEN
Every character is fully voiced, with an original score and sound that bring a rainy 1970s New England town to life. A storyteller guides you from the first page to the last, and he has a secret of his own.

FEATURES
- A branching story of about two to three hours per playthrough
- 16 endings, each with its own epilogue
- Replay any chapter you have finished
- Hand-drawn casebook art in a single ink style
- Fully voiced characters
- No account, no sign-in

PLAY YOUR WAY
The prologue and the first three chapters are free. Open each later chapter for free by watching a couple of short ads, or unlock the whole case with one small purchase that also removes every ad. No subscriptions, no timers, no energy.

This story deals with murder, grief and suicide and is intended for players aged 16 and over.

Recent changes:
You can now unlock the full case straight from the title screen and the pause menu. Small layout polish.
