Good job with the game!
Love the art and the sound design, I appreciate that there was no sound when moving, that would have become too much ha. When I was quickly moving from one screen to the next and going back and forth, I would feel sick from the visuals, if possible and the design allows for it, I would suggest a smoother transition as the player character moves, like keeping the PC in the middle of the screen.
Fun idea and I would love to see the themes expanded more, it felt like I was a mouse in a maze towards the end but if say there were firewalls or other things to avoid/hack, then that could elevate the game
