Reminds me of Rampage, which was a game about Kaijus that take the city's... But in this kind of game you need to feel that the player has weight, that when you hit a build, it feels like you hit a build or the cars. You can make this with particles, stop time, animations, etc. Variation when the characters walk. Ho, the first level has a glitch in the music, the second level don't but the music ends and never play again. Good work.
