Just had to go check re: rotation, but it is eventually multiplied by Time.Deltatime. But good thought!
I've played it on here to, and it still feels right. Think it's just going to be one of those things that It felt right to me because I've been playing with it from the start. Ship can do a 180 in less than half a second or something, though being a Lerp, does ease into the finish which might be part of it. Could it be more to do with accuracy and shooting the enemies moving at the same time (in that you need to lead the shot sometimes to hit the rock going past, timing the speed of the shots with the movement)?
I'm glad you made it to Cute animal land :D. Thanks for playing and feeding back. Really appreciate it!
