Pretty good start!
I had to dig way into the nether regions of my brain to remember where those ship sprites come from. Good ol' Klik&Play days.
Yah! I like how it is coming along. Just think I will have issues when it comes to pinning the ships in place and then getting them to do there random attack waves form a set position.
On last path ended / if enemy is playing - Move enemy uid to set position / wait time / then repeat attack loop or some thing like that.
I can see it in my head just have to test it in the real world. Have fun and enjoy. JC
