Go Happy And Smile

You control a character, moving left and right with the arrow keys and jumping to navigate platforms. The main goal is to clear each stage by defeating every enemy you encounter. You pick up different weapons along the way, and collecting money from defeated foes or items is a constant part of the loop. The controls are basic, with separate keys for attacking and a special move. The pace is fairly brisk, and the difficulty comes from managing enemy patterns and timing your jumps. It feels like a direct, uncomplicated arcade challenge.
