The space ship follows your mouse. Click to fire.
How many rounds can you endure? How many ships can you destroy? Face infinite rounds of groups of ten enemies to answer those two questions. Each round starts after 30 seconds, so don't give up waiting. Watch your health though. Getting hit will remove some! Of coarse, you can take five hits before your shield runs out. However, you will loose if the ships reach the bottom of the screen or if your health runs out!
