does it matter much? I&#x27;d suggest working in the language you know best. You can always improve performance of slow code. Struggling to learn a language and write a game handicaps yourself, because you&#x27;ve got to learn a whole language to express yourself. Computers are super fast now, you can write a fine platformer in any language. If you&#x27;re going 3d, the heavy lifting is handled on the video card.
