It is very well optimized, I was able to play it easily in 5K at max settings at a constant 60FPS, but honestly, it's to be expected considering the game's overall simplicity and it's low-level simulation complexity.
The only small problem is that the main menu of the game is 18:9 (because mobile screens currently don't really go higher than that), but at least it is not stretched, there will be black bars on the screen if you use a wider monitor than 18:9.
To add to the first point, the HUD elements show up correctly on the sides of the screen and there is no stretching at all. It's not really surprising, considering that it's first and foremost a mobile game that just happens to be playable on Windows 10 machines and as we all know, Android phones come with a bunch of different screens (in terms of aspect ratio) and the game has to support all of them. The game supports arbitrary resolutions and aspect ratios, such as 21:9 (2560x1080). I'll mainly talk about tech-related things but maybe I'll do a gameplay impressions post later after I played the game more.
Okay, I'll try to keep this as short and informative as possible.
