Ok, thank you for the reply. May be, it is because you did not reach the level 2. You have to collect energy balls to avoid a cataclysmic storm. Your conventionnal weaponry does not work for this stage. Collecting 3 EB and you launch an energy wave. This is the only way to damage the aliens. It is a bit explained during the tutorial. The fight during the level 1 is the root cause of the appearance of such entities. I decided to add a basic scenario to introduce this game mechanics. May be, this is too much. Actually, i guess that no one takes the time to read. 

Give it a second try to discover all the pôssibilities. But are you going to beat the boss to reach the stage 2? :)
