Wow, I really liked this one. I liked your take on the theme a lot! It's not just "attack enemies and they attack you." But rather, they target you with the same type of attack you used, and it was super interesting to play.
I specifically like the level design. There were lots of options for how I approached each situation, between the barrels, shooting, and kicking - it was like a puzzle game and a shooter (or maybe a stealth game?). The idea was really neat and you did a fantastic job designing the world around the idea. I'd love to see a full game with new attack types and world objects - that would be fun!
Of course, art and sound were top-notch as well. This is fantastic!
I also had a good laugh when I kicked a barrel and they did too... That was a really neat moment.
