I just finished
Contrast.
First of all, I would say it took me about 3 hours, perhaps 4 at the very best. The soundtrack is very nice, check some of the tunes in
here specially the first one.
The Story is...odd? And it made me a bit sad but that might be to the dark, depressing setting that takes place in 1920. The game plays like a film noir and makes good use of the Shadows in order to solve the puzzles, granted there are not many of them due the short time of the game.
Contrast is split in 3 Acts and each one can be completed in about 40 minutes but this will depend on how fast you are solving the puzzles. I did 100% on the game, unlocking everything there was to unlock. The end of the Story was very... confusing. You get a "What, that was it...?" feeling but I was already getting that since the very beginning. I guess that the objective was not very compelling from the start and the writing felt a bit amateur, in all honest.
Get it if the setting is to your liking and the price drops to a more decent sweet spot. The currently price is too much if you ask me. Best thing from this game to me was, as mentioned, the soundtrack, it reminded me a lot of the intro scene from another game: Saboteur.
