Hey REPTOfans,
I've been hard at work implementing enemy behaviour for ... well, longer than I care to admit, but a good portion of the total development time is spent on these guys.
Here, for example, is Acneopteryx.
This little dude is making that awkward transition from bumpy-faced reptile to beautiful feathery bird (but is obviously still closer to the former). He's trying to fit in, which means that when he sees you, he makes a valiant but mostly-futile dive-bombing attempt in your general direction.
So this is one of the first enemies you'll see, which is interesting, because it's one of the last I had left to develop. :)
