thanks for playing guys!
@ falmil & ohgr: did you understand that the meter in the middle of the screen is connected to when you are vulnerable and when the spawners die?
the meter goes up when you left-click to "devourer" the pluses and boxes you have collected. the meter goes down when you get hit by projectile (small dots and "erasers"

that follow you). when the meter is full you kill spawners, when its empty you will die if you get hit.
@ ohgr: no you cant kill the erasers. they like missles, but maybe that isn't to clear. will have to think of making that clearer.
@ falmil: when you say health are you referring to the meter in the middle of the screen? pluses and boxes are supposed to be recognized as enemies. when you collect them and then left click you get points. the more enemies you gather before you left-click the bigger your multiplier is and the bigger your score gets. left-clicking also charge upp the "spawner-killer"-thing and your speed boost.
will work some on how the colors and forms are interpreted!
