There was a harder enemy planned; implementation would probably be ~1 day's work modelling and animating, and at least another finagling them into actually being fun to fight against, going from experience with the Jam. Unfortunately, I was still implementing the Defender and some of the Interrupt orders even on the final day, so they got dropped.
I admit I kind of assumed the camera movement was self-explanatory because 'that's how it usually is', or so it seemed to me. Really, the game needs a tutorial in general.
