I really love the vibe of this game, I'm glad someone else went the action movie hero route! It reminds me of a lot of the games and movies that inspired my entry, though your art and game feel is way better than mine. The amount of energy put into polish is immediately evident, from the screen shake to the explosion effects and hit flashes. It's a little easy to just sit in a corner and keep firing without ever taking damage, some more options for player actions and some more obstacles to deal with could probably improve that element. But what is there feels very smooth and is very enjoyable, and the feedback from the game is very satisfying. I think you could take the core player mechanics and style, and turn it into a really fun full-length game.
