Really small text
Just the intro video stuttered
Greeted by an error for DirectX 11 unable to use any stock proton versions

The exact error is this: Failed to initialize graphics. Make sure you have DirectX 11 installed, have up to date drivers for your graphics card and have not disabled 3D acceleration in display settings. InitializeEngineGraphics failed
Using proton 7.0-3, all functions of the game seem to be working fine. The game now connects to the multi-player network. Haven't tried an online game yet though.

Installs and starts but no icons
No icons displayed making it unable to play. By Icons I mean all the graphics representing the counters etc.

Tutorial videos do not play.
While the tutorial videos do not work, the PDF manual is probably a better resource for learning the game.

Proton-5.4-GE-3 GloriousEggroll
After trying the mf fix without luck, I switched to the GE Proton fork and the tutorials worked perfectly. I am not sure if changing to the custom Proton uninstalled the mf fix or not but its working now. I had tried the Proton 5.8 with mf patch included but that did not work.

Plays normally, except the tutorial videos. Installed the MF fix but then it starts to load the video and crashes to desktop.
When loading the tutorial videos after installing the MF fix
game refuses to start with Proton 5-0.7 and Proton 4.11-13
Solo en los escenario sin refuerzos, y ya conociendo el sistema, ya que el tutorial no es funcional.
No se puede jugar el Tutorial. Las misiones con refuerzos no son jugales, al querer colocar los refuerzos estos desaparecen luego de elegir el lugar donde colocarlos.
Missions which require reinforcements do not work. The reinforcements will not appear. Tutorial videos do not play.

Gameplay seems as good as it can be apart from missing tutorials
Tutorial videos did not play.
Given the early access state of the game, the video-only tutorials are very basic, and not all that helpful for learning how to play the game. Hopefully they will improve but in the meantime it is at least as good to examine the PDF rules, or consult a youtube playthrough.

The game seems to work but the tutorial is impossible. So, may be, if you already know the game rules you can even play it...
The text in the tutorial was invisible
