Hello,
Interestingly I have a game made almost the same for Android (Java), so it is more than tested and works correctly. You should simply adapt it to your controls, graphics, classes, etc.
My name is Albert and I have a lot of experience in Java (Java Swing, Java FX, Android, ...). I have been a Java developer (and / or Android) for many years, I have taken courses and I have learned self-taught everything that the courses have not taught me.
Besides Java, I have notions of other programming languages such as C ++, VBA, HTML, CSS, PHP, Javascript. When knowing so many languages, although some only a little, it gives me a more generic vision when it comes to programming.
I can not specify more about this project because I do not have more information, what I can assure you is that I can do it satisfactorily.
Before saying goodbye, I wanted to thank you for giving me the opportunity to bid and I wanted to invite you to visit my profile or contact me.
I await any clarification.
Thank you very much and greetings.
