Buggy, monotonous and difficult.
Buggy at any level, had to restart regularly.
Monotonous - same ships appear in the same spot each time you come out of docking. Therefore, to level up, you do the same thing over and over again!
Difficult- some areas have superships that are impossible to defeat, so essentially those areas are off limits.
Overall, I have played and deleted this game twice, with the same problems each time…
