"Alex Kriss' surreal Twine text adventure Progression is strange... It's also creative. Frustrating. Evocative. Punishing. Mocking? ... Progression is well worth your time." -Jayisgames

"...a beautifully and very carefully written tale of two brothers' descent into an ancient structure." -PC Gamer

"Browser Pick" -IndieGames

"Guys I have been addicted to this game for a week now BE CAREFUL IT WILL CONSUME YOUR WORK LIFE" -David Sims, senior associate editor at The Atlantic
