There is a bug that needs fixing (I played Sweden). Germany performed twice.

What should I do after downloading the game to my phone, because it is probably an exe file and my phone does not support this type of file?

Wow! This game for sure was fun to play and watch the whole season pass. Maybe I would just change the graphics to something more pleasing to the eye (mainly scoreboads + add single revealing option instead of full qualifiers in semis) and not stop by one season (but maybe you'll improve it leaving the beta). Good job! You deserve more recognition.
