"A ton of new content has been created so far and the game continuously improves to match our high standards. Specifically, we have made many improvements to the game engine, drastically increasing the visual fidelity while optimizing performance. At this point we think the game's screenshots are starting to show the difference, but we haven't yet reached the final quality."
Enjoy!
