I had a good time with this. The customisation of the organism was great and the number of parts and upgrades allows for lots of varied runs. I had a great time zooming around and unlocking things after a few upgrades.
I will admit I was quite overwhelmed by the UI. It might have helped to be able to show and hide each section. I also think the sequence of input to take over the host was too fast but I'll admit I am not good at that kind of quick time event. It would of been nice to have some audio in this too.
Altogether, this is an excellent game. Oh and the intro cutscene was a fun opener!
