A good starting point would be to jot down any initial thoughts or ideas you might have, even if they’re not fully developed yet. Don’t worry about perfection at this stage—just focus on getting something down on paper, whether it’s a few words, bullet points, or even a quick sketch.
Based on user feedback about the game, it’s great that Basketball and Football are already considered good. You’ve identified key elements such as dribbling, scoring, passing, players, a timer, crab movement, and a goal to score points. Use these elements as a foundation for your ideas. Think about how you can combine or adapt these features to create something unique and engaging. Start by sketching out how the game might look or writing down how it could work, and then build from there.
