Poland-based developer Scriptwelder is a well known creator of creepy web-based games, perhaps the most iconic of which is the Deep Sleep series, which has won multiple awards and been played by millions all around the world. The Don't Escape series began as a web game in 2013 that inverted the classic escape-the-room formula... rather than trying to find a way out, players were instead trying to find a way to secure themselves within, usually from some sort of threat or danger. He recently released Don't Escape: 4 Days to Survive, his first full length premium game.
