Creating a flappy style game, i want to know your opinions on which menu design is best Screenshots is also posted to give you idea about gameplay
To be honest: none of them. Before you keep going take a look at other games you like and see how they did it. Then copy what you like the most. Also, try to observe closely how they use color and contrast and learn as much as you can about design aspects. If I had to choose I would go probably with 4 as well.
I'm with Christoph on these. Probably none of them. 1. Have you tested these on your phone? That would be the first thing I would do to check readability and size. 2. All one color doesn't offer much rest for the eye and the color combination is highly visually vibrating which can be tough on the eyes. Give the user a little bit of a break with the color you use and the contract.
Why not have the UI balls fall down to the floor and bounce until they settle? Have a colour for each ball
I would say definitely easier on the eyes. Now play with different colors for the characters. I'm just saying out loud the first things that come to my mind, so in the end, do what ever you think is the best for your game.
