Sure! Here's an example of a simple 3D maze game implemented as a single HTML file using JavaScript. In this game, the player controls a cute girl who is trying to navigate through a maze and reach the player's character to kiss them.
Please note that this example demonstrates a basic framework for a 3D maze game with a kissing mechanic. You can take this as a starting point and add more features, levels, controls, graphics, etc., to make it a fully fledged and enjoyable game.
