I really enjoyed this demo. I had a couple of small issues come up which I'll list at below, but on the whole I thought the graphics and sound were really nicely done, and the creative design of the final boss in particular was great.
Small bugs:
- The cinematic view camera was too "greedy" at taking over, and also interrupted the first boss fight
- The second boss fight's charge attack failed to lock its direction once, and he charged at me even though I had moved. Also, once it killed me when I was way outside of the indicated rectangle
I look forward to seeing what other abilities the creature might gain. The idea of a spore-like evolution is interesting. There's also the classic RTS "Impossible Creatures" that did something similar.
