Please keep in mind that the game is still in production phase. Certain things are still being worked on. The final version of the game will look better than what can be seen in the latest screenshots no matter the platform. As you probably know, when publishing screenshots, some of them can be subjectively less appealing than others (depending on ones opinion), thats perfectly normal. The most important thing here is that the game will come out looking gorgeous when we are done working on it. There will be no downgrade.
