Neat concept to put into 2D, though I've never played a swat game before to compare. Audio, menus, and animations serve their purpose decently. Arresting takes too long, especially when contrasted with how a fire fight killing 10 people can happen in a second. Enemies wandering into the swat team within 5-10 seconds of loading is way too fast, maybe undesirable to happen at all. It makes sense for them to wander since they don't know the swat team is there, but I think it's a bit off putting to be surprised as swat, instead of surprising them if you wait a short while to gather your senses.
I was also able to see the doors swing open though the fog of war, which allowed me to know where an enemy was walking, if you can it should be preferable to hide the position of the door unless it's in sight. If you want to be fancy, the fog of war preview could update its position to where the door was when last in line of sight, so it stays accurate until someone interacts with it out of view.
Looks promising.
