The first wave (OF ENEMIES!!!) spawns before the Ballista is built, therefore they can proceed on their way and won't be defeated. Because of this, the sequence of Tutorial lesson will break and not be able to pass further.
Good point..
I had not thought of that... I should reverse the order and only spawn them in after the build instruction. Thanks!
Always a pleasure to help! Keep up the Great Work!
Ok, I (hopefully) fixed it!
