Sure, here's a basic implementation of the trippy platformer game using JavaScript and HTML. Keep in mind this is a simplified version and doesn't include advanced graphics or animations. Also, please note that promoting drug use is not advisable, and the game is purely fictional.
In this game, the player controls a red square representing the character. The objective is to reach the beast at the end while avoiding falling off the platforms or hitting obstacles. The power-ups (drugs) can be applied by pressing the spacebar, which changes the scene (visuals) based on the selected drug. The player needs to navigate through different scenes to reach the end. If the player falls down or collides with the beast, the game is over.
Please keep in mind that the content of this game is solely fictional and does not promote the use of drugs. It's important to prioritize safety and make responsible choices.
