🕹️ Game Development

Use "responsive" UI design from day one. Make graphics and UI supports all the aspect ratios without breaking. This is not only for web games, consider doing this way for all games. It's a lot harder to add multi-resolution support later.

Support multiple input styles. Try designing game mechanics that support multiple input styles. Mouse, touch, only keyboard etc.

Iterate fast. Start with something that you know so technology isn't a blocker.
