Really interesting idea.
I liked how many different actions there were, but I'd have liked to see each one explored more. A lot of the later puzzles were really hard because I didn't understand what each mechanic did. I assumed kicking people through windows would hurt them, and I never really got why I would kick a door when I can phase through them.
The tutorial prompts were great, although it took me three levels to realise there was an ammo counter. I was so focused on the timer, I didn't notice there was another lose condition.
Overall, really cool concept, nice aesthetics, possibly overscoped.
