I like the movement, it makes traversing the level a puzzle and it forced me to think about how to get to places. Good use of the theme - when the time was running out, I really felt the pressure of finding a door and getting to it.
Ideas to try:
1. Speed up the game by increase movement speed and reducing the timer. I think this will make the game more engaging by reducing the boring time of walking. The player is more likely to try again if a round is quicker too.
2. Add an option to bypass security. Sometimes I get stuck between two things I can't cross. Maybe it's a dash that has to be timed right, or a limited resource.
2. Zoom out the camera more, so the player can see further and have more option to plan their path
3. Place a computer near the spawn, so the player gets practice right away.
Overall, very good execution on a creative idea!
