A unique and fun take on the theme that I had never even thought about myself. Awesome work! I really love the camera mechanics and the calling the guards mechanic too. I feel like it would be even better if we had a map of the store so we know where the camera are pointing to.
I had a few issues on my end however and I think they might have just affected me judging from everyone else's comments. For some reason, some of the customers suddenly stopped moving and stopped me from progressing the game until I used the security guard to clear them. This happened on day 2 and on day 3 the same thing happened however I could not progress even after I had used the guard to clear the level (maybe there were some customers off screen that I couldn't see that had also stopped moving).
