Welcome to the forum.
Good to see games from Android developers from our very own country. Idea of the game is good. The game needs a lot of work though. Some annoying things which I experienced while playing the game:
1. The friction: Striker takes too much time halting (coming to rest) after we push it to hit objects. Like the animation of hitting objects finishes in maybe 1 or 2 seconds, but striker keeps on moving slooooooowly for the next 10 seconds. Makes each try a little more boring.
2. The prompt "Score XXX to win this level" seems unnecessary popup
3. The jump from after we finish a level to main menu is awkward. Maybe next level should automatically load, so that user is engaged.
4. If you press back and quit while playing the game it closes the entire game and brings you to homescreen. Why? It should technically take you to main screen. And user should be able to then quit from game from Main menu.
Personal point:
5. Fonts.. (is it Jokerman?), they look funny. You have got to find some other font
Besides all the points above, graphic elements can also be enhanced. But I guess this is just ver1.0 of the game right?
Good luck for your endeavors and apps.
