Interesting idea, the boss is cool and gives the big bad robot feeling, very funny to punch it and see it fly away. Live camera is an hilarious and genius addition.
Loved to jump over buildings to pick up bonus, health boxes and shooting down enemies.
I'd liked to have a free aim for mouse and keyboard play instead of only locked target, but as an android game it work well.
The game sounds has some mixing problems, some are high while others are way too low, especially player sound like shooting.
Normal enemies also are a bit too static, giving some paths to follow would make the city way more lively.
Building are a bit anonymous without textures, but finding good ones in a short period of time is hard, so no problems.
Overall it's good and it follows well the theme in a very unusual way.
