What is a Java snake cookie clicker?
This is my first graphical application I have made in my life (except HTML and Javascript-Applications, if that counts). It's a simple implementation of Cookie Clicker, the famous browser game. Unfortunately the size of the buttons equals the size of columns. That does not look good. I have seen a solution that uses two layouts. A GridLayout, and an additional FlotLayout. But the code looks so ugly, that I don't want to use this way of programming.
I would be very thankful if you have tips for me on how to improve the code quality! Programming a graphical application is much harder and more complex than writing textual applications.

i like the focus on responsible tools, since deposit limits and reality checks are the only things that keep my sessions sensible. ai tips sound interesting, but i’d be wary of people treating them as a shortcut to “beating” the casino. i’ve played a couple rounds via https://xxxtremeroulette.com/parimatch-casino/ and ended up using time limits straight after because the xxxtreme lightning multipliers hit so fast it’s easy to lose track. similar deal when i tried funky time through https://funkytimegame.org/mostbet-casino/ ; the bonus rounds and energy make the reality check pop-ups feel necessary. then jumped to crazy time on https://crazytimegame.org/melbet-casino/ and same thing — those big wheel spins fly by without the timer i’d be gone for hours. overall, the tools matter more than the game math if you want to stay in control.
