While the game is great i've had trouble with the pixelated theme of it, its a bit too pixelated for me that is all the feedback i could give i expect most of my other feedback to be already in mind to develop.
I definitely second this. It was very hard to tell the difference between my vehicles and the ground because of that. Some pixelation is probably fine, and the game's aesthetic is great, but maybe a screen filter or smth would be easier on the eyes than pixelation. If the game looked half as clear as that final screenshot does, it would be 100x better. Imagine being able to visually see ERA detonate or a shot ricochet, rather than just being a bunch of vague pixels.
Also, I don't know if this will help anyone, but use ctrl + left click in order to order your units to move backwards. I don't know if you can chain reverse and forward gears in the same line, but it would be a cool feature.
edit: also, a mode that lets you switch between infantry view and tank view would be good in order to see what pathways your tanks/infantry can take at a glance, without needing to dismount first.
What resolution is your monitor at? currently there is a graphical bug where the pixelation shader "pixelizes" way more at lower resolutions like 1980p, compared to 2560 or 4K, this is on my todo. And at the end of the day, the stylization does lower the amount of work it takes for me to create VFX, textures, and effects.
A mode to toggle or show views without selecting infantry is a good idea!
I run two monitors, 1920x1080 and 1600x900. It's hyper-pixelated on both. If necessary I could get pictures/video of the problem if you need.
I do hope you are able to go into more detail in the future, when the game is more complete; definitely focus on playability, content, and anime waifus first!
I also have one more suggestion, add a Stryker APC to the game. I was a little sad not being able to take off main armament and switch them around, but with the Stryker it was designed to be "easily" converted between APC, IFV, ARV, MGS, and other configs. Would be awesome with the modularity of the game! Also probably best to wait for later.
