I really liked the cyberpunk style city in the background as a wave of code is chasing you, I thought that was neat and I also really liked the music.
I had a bit of trouble with the stickiness of the walls early on, but by level 5 I figured it out and really liked it. Great job!
Also i tried and died soooo many times on level 5 to get up the tall tiny shaft by wall jumping, I never made it, but I liked having the option to try (even if it was a trap lol)
