This is cool, i think a little more messaging to the player would really bring out the concept of this game!
The cameras and lasers intuitively made sense, but it wasn't immediately clear how the guards worked. I thought their detection was based on line of sight and that they were looking in the direction they were moving... until i got caught. So if you want that to be immediately understood by the player, you might need some game UI like a circle around the guard. I also found myself wanting a message about my objective before the level started as well-- wasn't sure if i just needed to collect all the gold, or to do that and reach an exit. It was fun and satisfying to dance around the rotating cameras though! It was also fun to try to plot a route through. I think the 'get caught once and you're dead' difficulty was perfect, and I appreciate that there were multiple levels designed.
Overall nice work, there's a fun game here!
