Prisoner

Developed and published by Polovey Alexander.
In Prisoner, you'll wander around in a strange place with many rooms — a place in which you are a prisoner. Things move around, and you hear strange sounds, but be careful whilst you follow the noise, as there are tons of deadly traps.
Escape 
Your only goal is to make it out alive from this strange place, but it won't be easy despite sounding so. There are enormous amounts of levels, and all the rooms move around. The worst part? You'll never know how they'll be when you see them again.
Death Everywhere
There are tons of deadly traps just waiting to spring on you and end your run. From steel blades to laser launchers — you'll have to keep your eyes peeled and your reactions quick if you want to leave this place.
Step By Step
Discover the two endings that will grant you access to new levels, and carefully explore the area to get to know it. The trials will be difficult, but you can take it at your pace.
