Very interesting puzzle game based in a city-builder or builder surrounding.

You first place your base, an upgradable medieval district, where you could do research of new techs like buildings (houses) or gathering which are represented by card or item decks from which you then place tokens on the map. There are different modes, just for fun, level system or even multiplayer. So far I only played level system which teaches you into the games system and how to achieve new maps with more tech to research or more and interesting challenges to solve. In your first level you only have housing and gathering tech, but each tech could be expanded when reaching a given score. At housing you may gain wells or townhouses for other upgrades, at gathering you possibly gain hunting, wheat fields or cows. The better you place your tokens on the map, the more you score. But that isn't all, there are so far hidden upgrades, like placing 3 gatherers adjent to each other and you gain a fruit farmer which scores additional points for your tech upgrade but also for your tasks to solve the whole map/level you are actually in. There are a lot of hidden upgrades, each with an unique combination of different tokens - three wheat fields and a house turns into a farm - or other combinations. Quite interesting to figure out all possible combinations and finding the possible spare place to realize them on your actual map. You have to place your tokens strategical, otherwise you might not be able to finish the level or would not be able to generate new decks with tokens to place.

Not tested multiplayer, which tells to offer competetive or coop, or free play so far.
The game is demanding and holds you focused for a fun and relaxing game.
Recommended? Yes, if you like puzzle games, finding secrets by combining tokens on the map into an upgrade or achieve new levels. It's not the typical builder game, where you just build your kind of paradise in the wilderness...well, I guess, because the free game may offer some kind of that...

If you can get it on a sale, you can't do anything wrong.
I'm running it on linux system without any issue, so it's Proton approved.

Fun little puzzle game

Not my thing. Maybe someone elses thing, but not mine
