Fun!
Swat in 2d is a great idea. Regarding the demo, there's A LOT of actions and things to do, it got super overwhelming quick and i dont think players will remember all the things in the tutorial by doing them once. I would have prefered if you introduced things in levels and then had 1-3 levels on that one thing (grenades, commands, cover etc).
You got all the building blocks just need to smooth out the journey a bit. Good job, will follow!
