I'm a solo developer. Three games in the Project Dream series so far — same Soviet-era facility, free-roam first person, built in Unreal Engine for Android. On the side I make fan games — seven of them on GameJolt, mostly for PC. All free, no paywall.
One facility, two survivors. The prequel follows a maintenance worker on the night shift, back when the lab still worked. Chapters 1 and 2 follow the same person — the one who fell through the floor and never made it out on the first try. Each chapter stands on its own, but played in order they tell a single story.
The rule across every chapter is the same: you walk the corridors yourself, and no scare waits on a timer. The thing down there patrols the facility. If it catches you, it is because you took one wrong turn — not because a script was waiting for you to reach a trigger.
Every message gets read. If something broke on your device, include the phone model and which chapter you were playing — that is usually enough to find it.
