This is a pretty good game, I could see someone playing this for a good while. Shooting enemies is fun, yeah; I even got a double kill once. I think the movement's okay, but the jump seems weak compared to the player's running speed, so you could either make the player slower or make the jump more powerful. There could be more audio, also. There's guns but no gunshots. Also, this doesn't seem to fit the theme of Summer Simulation-- if this is what your summer looks like, then you've got one intense summer. Other than that, it's a pretty good game! With a bit more polish, it could be even better!
