Try to add particles effect , post processing , trail effect , textures , and make the controls little bit fluent and make ur game little easy. Btw good work.
I am very much grateful for your advise . I will apply all your suggestions as soon as I get laptop back. But as I am in very much need of a Google play console account so I borrowed laptop from my friend for only 2 days and work hard on this game . This is the best i can make in 2 days . I will apply all your suggestions as soon as I get new laptop or I will borrow it again.
Again very very thanks for your ideas. I am damn sure if I apply this suggestion in my game , then game would be great. I will surely try to update.
