Everything is thought out very cool. I am just learning to write games on Fiton and not only. In the future, I would like to create something with online games. I always have holandia kasyna as an example, I read about it https://pl.bestcasinos-pl.com/holandia-kasyna/ here. This would already be an achievement for me. But I can’t imagine how much more effort I will need to spend on this.

Change each of the letters for up, down, etc in the "onkeypress" statements to correspond to the literal words "Up" "Down" "Left" and "Right" in place of the 'wsad' options, and you'll get keyboard arrow functionality.
