Machinarium is and adventure game from the hands of developers from Amanita design (who are my fellow countrymen) who are responsible for couple of very well accepted adventure games. Machinarium is another one of those and it can boast a very cute, original and !lovely! art followed by a very decent soundtrack.
Adventures are usually a story driven games and Machinarium is no exception, though compared to other adventures it is quite exceptional. There is not a single line of text (spoken or written) and the story is narrated with the use of comics bubbles showing thoughts of characters in pictures. I would not like to spoil anything and my memory is also a little fuzzy since I have been playing the game with months worth of pauses so I will not dig deep into the story, but to outline it a little I will say at least a bit. You are a small, male robot who has been separated from his sweet robot "girlfriend" and you have to find her. To do so you have to travel through a robot town doing the usuall adventurist stuff like using and combining items.
As for the art itself, as I have said, it is really cute however overally the locations and characters are actually depressing, very dark and negatively industrial. This leads to pretty mixed feelings because on one hand you admire the cuteness of the drawings, on the other you feel sorry and sad.
What I cannot vouch for is the design of the puzzles. They are not insanely hard, actually you will probably be able to guess what you are supposed to do pretty fast, or that was at least my case, however the steps needed to get it done seemed pretty much random and I did often struggle with them. There is nothing more frustrating than knowing the answer and struggling with finding the right paper to write it on. Because of that I often had to resort to using the build in hint system.
The hint system has two levels. Upon using the first level, your little robot will pop a thought comics bubble and give you a small hint usually pointing out what it is you should do in the current room and you are to find a way to do it yourself. This may help you, but as I have already said, figuring out what to do is not much of a problem, but how to do it, that's the question. And that is what level 2 hint is for, if you are really desperate you can use it, but in order for it to work you have to finish a small mini-game which involves navigating a key through areas and monsters in kind of a side scrolling shoot-them-up (like Space Impact on old Nokia cells). Upon finishing it (and you will probably hate every second of it, because it has terrible hitbox and is just no fun) you will be given a comics like page in a book showing you step-by-step walkthrough.
So to sum up, I did like this game to an extent mainly because of the art and soundtrack. Story was good enough but I was really annoyed with puzzles and the hint system. I do recommend you to play this game, but I would say, don't feel a shame if you want to grab a hint or two, or rather get a walkthrough on the internet (if you hate the minigame required to complete for the hint as much as I did) when you are stuck for unreasonably long time.
