Unbalanced, unfun.
Level 13 is where the annoyance began. The first half of the game started out fine. Easily avoided enemy fire, boss battles were a challenge. Suddenly, an onslaught of ships that gives me roughly 14 seconds of gameplay before i watch my little spacecraft helplessly bombarded. What happened...?
The option to reshuffle the points around is a bonus, but hardly useful. Visuals, quite interesting, but the overall gameplay is just...redundant, and suddenly a rage filled scream-at-my-monitor fest. Tweak it a little if you can...
