Fun, addictive and challenging!
I had a lot of fun *trying* to get to the top of the scoreboard. The randomness and variety in enemy ships kept it interesting even after playing for quite a while. Every attempt had an unique feel to it, as the enemy waves and powerups were completly different each try, still keeping an overall pattern and difficulty curve in check, well done!
There were a few "unlucky" and "Why do you hate me game?" situations which truthfully were hilarious, a bit of bad luck and poor planning leading to an epic failure ("Well , damm"). It may seem unfair at first but it gets better as you keep going, learning how to avoid those situations thinking ahead and dealing with each enemy type better. For me, challenge makes it interesting so I am eager to see what else the game will throw at me as I progress further! Slowly but surely!!
