We have similar ideas! I was a little bit confused how to tell who's shop lifting at first, and accused a few innocent people haha. It felt a bit strange using a/d when the shop kind of matches vertically (i think?), but that's just me and it didn't break the game or anything.

4 shop lifters got away. But I must confess, I've not bothered looking at the security cameras except for the one at the exit and just arrested everyone who didn't go to the cash register. I just didn't react fast enough to let those 4 slip. 0 wrongful arrests. To add a bit of  a wrinkle to it, would be cool if some customers just aren't buying anything so I can't just be waiting at the exit and arrest anyone who's not going to the register. Enjoyed myself nonetheless and theme is on point!

Shop security guard - that's one stressful job! The game is good in showing that. Interesting take on the theme, cosy visuals, relaxing shopping music. Fluid animations. Some escapers seemed impossible to reach - it might help to let the player change the guard's standby position. The other camera seemed to serve no purpose. I found no way to start another round other than reloading the browser tab.

Its so fun but there are too many npcs 

I see the idea. would be a pretty good game with some polish. Well done
