I remember.Next game, I well listen your commend and make this better then this.but tell me... how you do that? you said reached to level 17??! but how..? I can't reach level 6 but you reached to level 17... . nicely done dude!
It's as simple as staying in a corner and just clearing the path in front of you (because you don't need to destroy all enemies). If the enemy shoots, just dodge and go back to the same spot.
