When launching the game you'll get access to a menu allowing you to start a game (of course), to setup your preferences and graphical settings. Here's an overview of those options.

On the left you can set the resolution for the game. The higher it is, the slowest it may be depending on your graphic card and system.

Windowed Mode: Allows you to toggle full-screen mode on/off.

Show FPS counter: Show in the bottom-left corner of the screen an approximation of the number of frames per seconds that are displayed.

Disable Interpolation: May very slightly reduce the quality of the image to very slightly increase the FPS.

Cap FPS to 60: Recommended! This is a top down 2D game, you don't need more. Depending on your computer, disabling this setting may render the user interface much less responsive.

Enable Bloom Effect: Experimental! This is not a recommended setting, it will improve the output noticeably but it is buggy at the moment and may cause the output to flicker a bit.

Animated background stars: Amount of stars that are displayed in the background. Reducing it may improve performance on very old hardware.

Sound: Set the volume of sound effects (not implemented) and the music

The left panel allows you to change the default keys to your liking. There's currently a weird bug where the key you type may appear in the bottom box in some sort of Japanese language, ignore it, the game will use the correct key you typed.

Show targeting lines in sector map: In sector map mode, red lines will be drawn between fighting ships and blue lines between ships that are flying together if checked.

Debug: Enable Event Logging: If checked, the game will periodically save a log file in the “debug” folder. Check this if you are planning on reporting bugs on the forum.
