I liked the dynamic voice updates and it felt good blasting the hundreds of ships! I survived until wave 4 the first time, but the second and third time I played it wouldn't let me progress past wave 2. Regardless, that was a really time!
So sorry about the bug, seems one slipped through. Thanks for playing though, I appreciate it. :)
I've just uploaded v1.1 which fixes the bug you had. :)
