Ultimate Flash Sonic Overview
You control Sonic, running through side-scrolling levels filled with loops and enemies. The main goal is to reach the end of each stage as quickly as you can. You press the arrow keys to move and the spacebar to jump. A specific mechanic lets you perform a spin dash by holding down, pressing space, and then releasing the down key. The game moves at a fast pace, and the difficulty comes from timing your jumps to avoid obstacles. It feels like a simplified, immediate version of the classic platforming experience.
