Space Invaders: Galaxy Shooter

bad

the game is nice including graphics are very good now when I reached level 9, almost all the gold finished and had no where to gain. To go to the next level need to have 20 star's and I had 12 stars so it wasn't possible to penetrate next level. Also the main ship is moving slowly more like skipping or the network is bad when trying to move fast. Also some functions doesn't seem to work/upgrades such as ship speed... the all group system settings copse please fix!!!!
