@Oreon Necris I have the same predicament as you had, Any info you can remember will be helpful.
For anyone who didn't see, My ship spawns in the top left corner and I get an error saying "Symbol=EnemyShip, layer=Layer 1, frame=1, Line 1 The class or interface 'EnemyShip' could not be loaded." im running CS5.5 on a windows vista.
The enemy also does not move. I have codes exactly how it says in here.
Levels 1-5 Oh yeah, this game is easy.
Levels 6-11 Okay, this is a little more technical, I think I might be able to get the hard badge.
Level 12 I didn't need the 30 points anyways...
there´ll be a level editor in the next update (of the full version)
