Sorry for the late reply! Normally, I get notified of this by e-mail!
Okay. So the game starts with the company logo, then followed by a disclaimer. Once the “ENJOY!” is visible you can press any button to continue. Then it jumps to the OviVixen Title Screen. From there, you can simply press [L] to continue the game, or you can press [>] to look at and/or change the controls. You can find this in the Readme as well just for a quick refresher.
