Pixel games are a very classic category of games. In the past, when the level of technology and hardware was not high, a lot of interesting games were created to satisfy people's entertainment needs. Due to the limited hardware level at that time, the characters and animations of the games looked like a frame by frame, so they were called pixel games.
Then today, even though the hardware and technology have improved, people still miss the old games.
Pixel games are based on today's state of the art, still using a pixel style for images, emphasizing clear outlines, bright colors, and a unique graphic style with a variety of grainy pixels, while the look is often more cartoonish. Pixel is a unique nostalgic style of painting, just like Q-format or graffiti style games.
