The controls on this were rock solid.
Everything that is in just worked and it was lots of fun to play.
Was there any waves passed the 6th or 7th?
It locked up on me around there.
Aww man, sorry about that. Glad you still enjoyed it! It goes up to 20 waves, but there's just the two enemy types for the entire game so other than a bit of chaos you probably got a good feel for it.
