The game has numerous flaws, and summing them up, its cost is unjustified by far. If it'd cost several dollars, it'd receive a 3-star from me. The worst thing is the story itself. It's very shallow, predictable and its general idea of poor misunderstood children, hurt by big bad adults is placed comewhere between hypocrisy and ridicule. On the good side is graphics (nothing special, but good) and decent development system. But the pathetic story and sky high price place this game in the list of worst games I ever played (forcing myself to finish them).
The game's rating here is drowned down by reviews like that from someone @fawexx, which is either troll on russian propaganda's pay. or "useful ...". Personally I'm sure it's the first, because it's extremely hard to believe that 'Pole', as he refers to himself, would project russian WWII fake narratives with such determination as to blaming Poland in starting the WWII (but it 100% coincides with modern russian propaganda). As for the game itself - it's flawed, with rushed conclusion (even so it seems to be deliberate choice due to as the actual history of the event was) and obviously low-budget. But it's also solid on the story, giving the immersion in the atmosphere of desperate resistance against an overwhelming odds with the full understanding that the entire effort is doomed - but not futile. Saddening, but sobering and strong. The art is fine and the mechanic, especially strategic (district management) is surprisingly innovative and good. Overall, it's definitely good one-time play with distinct historical drama immersion, which is a rare sight in modern game dev.
