Press B to make your character bigger and S to return them to normal size.
Left-click your character to cycle forward through color options and right-click them to go backwards.
Press H to put on helmet attachments. You might have to press B or S to make the attachment match the size of your character. Press C to put on chest attachments. Press G to remove all attachments.
Press M to mute audio, and U to unmute it. You can also mute audio and then play this song: https://youtube.com/watch/afwNIRwDies
Press L to turn on light theme, press D to return to dark theme. Press Spacebar to turn off the background entirely (highly recommended for when you take the perfect screenshot for editing out to save your custom character).
Press Backspace to restart the level (each Armor Core is in its own level), P to pause the game (click to resume), and press ` (backtick) to restart the whole game and return to the main menu (do this to switch Armor Cores).
