Enjoyable
This was a great game! The only thing I would suggest though is to increase the speed and frequency of the enemy spacecraft a little bit. It was difficult to score more than single kills, especially because they tend to hover near the edge of the screen a bit before coming to the center of the stage. I absolutely loved the background, it was perfect, and I got distracted a few times watching the people get sucked into the spacecraft! Overall this was really well done, I enjoyed the sound-effects a lot as well! Good work, Great game!
