I have tested and what I can say is:
-The icon on playstore is horrible (this is the first thing that people is going to see). Seriously, I will never click on that icon, because it makes me think that the game is going to be horrible. You have many images free of copyright related with football.
-The same happens with your featured graphic, is a screenshot, once again look for something copyright free and make something fancy here.
-Its going to be difficult to get visibility on playstore, you have to include your keywords 5 times, for example you only have 2 times the word "soccer". Make a good description of the game with the most of the keywords related with soccer will help to gain some visibility. You can use free web programs as appanie to track your keywords.
(You can run experiments from your store consele with this 3 parameters and you will see you will gain some visibility)
-The game is boring (honestly), so the only way the people playing your game is with a very good graphics. Now you can see pixels everywhere.
-When I touch the ball I don´t see the walls, so I have try to put my mobile on landscape but its not possible.
-The animations are ok and run smooth.
-The music is hard to listen for more than 1 minute I want to silence.
-The UIS could have a better design, for example making a frame to the big Tiled Background where you put all the texts.
-The game is repetitive, you don´t add nothing to make it more tricky as you get points.
-Mobile Advert is showing ads ok, I have seem one.
This is my honest opinion. Good luck and keep on developing
Thank you for your honest feedback.
There are issues with mobile performance, If there are too many large, hi-res graphics, so I have gone for a low-res pixel compromise, also it uses the physics behaviour, which kills mobile performance on android 6 and below, so sacrifices had to be made.
I agree with the icon and screenshot, I will work on that.
I might add a frame , but wanted to keep it simple.
May I ask what device did you play it on and what version of android?
Anyway thanks again, I'm off to try your games now.
