Impostor War - Rescue Crewmate Among Traitor for Android

In each level the player is offered to rescue crew members from traps placed by a certain evil betrayer. There are locking bars on the playing fiels. They hold water, lava and the betrayer as well as other substances. 

To rescue the needed characters and destroy the betrayer you need to open locking bars in the right order. You can't control the movement of characters - if you open the bar that closes the way to the trap, the character will get into that trap for sure. The game offers about a hundred levels and point counter.
