Hi!
1. We are planning to add a toggle feature for fullscreen/windowed mode in the settings. Currently, this can be achieved by using the native Windows shortcut, Alt+Enter.
2. We also planning to add which the game will automatically switch to the default language display based on the system's language settings.
3. At the moment, we do not have a viable solution to enhance the hitback mechanics in gameplay. It is crucial to balance this feature carefully as it can negatively impact gameplay if it's too strong or too weak.
