Cheers for uploading the game, I had a fun time playing it, I see lots of potential for this enemy detection system, I feel like it could be utilised and refined in the future for the next games you make.
I do however feel that the game wasn't balanced as well as it could have been. There were many instances where I thought I was being sneaky and still managed to get detected by the police every time. The first 2 or so kills feel stealthy, then it quickly turns to a mad dash to evade the police, grabbing as many additional kills as you can.
Just a couple of hours of tweaking is all it would take to improve the play experience drastically.
Thanks for posting the game,
