One of the most successful indie games around is definitely Lumino City. The studio that developed it, State of Play, took it so seriously that they even ended up building all the settings with paper and cardboard.
One of the best indie games for PC
Its nominations at the BAFTA awards have turned it into a reference for gamers and almost a cult game according to different critics that have reviewed the title. In this game we'll have to solve all sorts of puzzles and mechanisms that will help us to move around a rather unique world.
A game halfway between coding and arts and crafts.
Sky gardens, water wheels, towers... all these elements and plenty more are part of the settings of Lumino City, that has also been a hit on other platforms like Android, iOS and Mac.
This adventure game, that has a high dose of difficulty, although it isn't completely impossible (in any case, we can download a tutorial from the Internet), will delight everyone with its enveloping atmosphere.
