At first, I didn't expect much because it seemed like a very cheap production, but Nightmare of Decay was a very successful production in its own right. The game is full of inspirations and references from many Survival/Horror games, especially Resident Evil, Silent Hill, Amnesia, Cry of Fear. The game has simple puzzles and some okay boss battles. Even though the story is a cliche story of escaping from a nightmare, I didn't care much in a game like this. One of the points that surprised me was that such a game took up 100 MB of space, because there are many sounds and places in the game, and assuming that it was 2 hours long, it was a very successful job. If you like the Survival/Horror genre in general, I can recommend this indie production.
