I love the premise. I'm a sucker for cyberpunk stuff. Felt like neuromancer, hacking a corporation in cyberspace. Maybe that was my imagination.
Getting caught on corners felt a bit punishing. Maybe the collision shape should be capsule instead of rectangle, or maybe you could implement a corner-slide mechanic to make it a bit more forgiving. Pacman style games would allow a player to hold the next direction slightly before they reach the corner.
Very cool game though. Fantastic entry.
