I liked the sprites and animations for Vedal and Evil - that being said, I disliked the hacking mechanic! It's frustrating when you're finally making a successful jump and then your inputs get hi-jacked, and makes an already tough platformer even tougher.
Speaking of which, it feels like I can only jump on Neuro's head when she's jumping - so waiting for her to jump once she's in your position was a struggle. I did like how forgiving the time-slow bar was! made life a tiny bit easier for me since I suck at platformers.
