Monochroma is a very interesting platformer. Without any story told, you will pickup your little brother and help him go through all the obstacles you are facing and escape from bad people.
-Graphics: The graphics are REALLY good. I love the black'n white with hint of red style. Feels reqlly unique (despite this is not the first platformer who offer this, check out Limbo an excellent platformer).
-Sound: The music is really good, feels like 1950's musics, with a bit a jazz, it is a good experience for your ears.
-Puzzles: Puzzles feels rewarding when solved, almost all of them are well designed, there some that could use a visual hint or two (like the double lift, I was looking at the wrong solution for quite a long time, had to look up for the solution as I couldn't see it but just the one I was trying which at some point seemed possible). I tink sometimes visual hints to go backward could have been good.
-Story: Despite being without any background, this is a success I think. You understand things one bit at a time, the background is the narrator. The story told here is not very big, it rely mostly on helping your brother. You get attached to that task.
-Controls: Controls are sluggish at time. It is not that important except when you need to do timed jump, and at that time the game gets frustrating. The tutorial was not clear enough about the jumping system, as I was succeeding all my jump, I didn't give any thought at first, and then you are in a chase scene and you need to do thing fast and it is not well responding, then you start yelling at your jump. Specially on the achievement Conscience to save a robot from crushing under a press. Looked up a playthrough online, and the layout of the button was different from mine (perhaps a different build than the final one), You have to do some timed jumps and be very reactive, I was trying really hard for at least 15min, then doing more or less the same thing as before, the jump activated as wished and I was able to complete it.
I should'nt stop you from completing the game but a bit of polishing on the control would have been good.
-Bugs: I found some bugs, mostly collision, when that happens you are a bit in a bind as you have to restart the whole checkpoint, despite them being well spread it's still a bummer.
I finished the game in about 4h (a bit more with the achievement of the robot), found 9 out of 16 secrets (I will probably look up for info in order to get them all).
Will you, like me, help your brother? I do hope so.
I do recommend this game to people who like platformers (specially if you liked Limbo, this one should be in your taste).
