Carto is a little girl that must find the way back to her grandmother, using the world as jigsaw pieces as she find them through 10 episodes, with an approximate duration of 30-40 minutes each.
No problem here. The game is beautiful and it has an excellent character design. They are all adorable. Looks like you're watching a Nintendo Switch game, but despite its appearance its not a child's game by its level of difficulty and by the amount of text you must read to finish it.
The story is not epic but it is quite entertaining. Characters have a lot to say and you must hear them in order to advance in the game. Thank God you can speed up the dialogue so you don't waste a lot of time with that.
Half of the game is like a classic RPG: you go around a place, meet people, talk to them and collect items that will be useful later. The other half is solving puzzles that can be very entertaining at first but then become quite complicated. The most agile minds will not find much of a challenge here, but the rest (like me) may have a difficult time playing.
If you want easy achievements forget it, this is not your game. The first 10 achievements are unlocked simply by playing, but the other 10 you might never find them, so get ready to play it with a guide of where and how to get each one. Especially the last two, as they require certain tasks in which you could fail and have to play the whole game a second time (or even three times). So if you love difficult achievements, you can change the rating from 6 to 10.
Carto is a good game but its difficulty could scare players away. It can be frustrating sometimes, especially when you've already tried all the options you can think and it turns out the solution doesn't seem to make any sense, but the feeling of having found the answers is rewarding. This game could last more than 10 hours, whether they are fun or painful is up to you.
