I loved the graphics and audio of your game and the animations are excellent, great work, although there are a couple of issues to fix
1) you left an entire useless HDRPGameJam_Data folder in your final build. It only increases the size of your game and serves no purpose. If you wanted to change the name of your project from HDRPGameJam to Time Rescue, you could just change the name of the exe and the _Data folder
if you erased HDRPGameJam_Data, your game would weight(compressed) just 109MB instead of 276MB
2) Walking and running speeds are too slow, and you go faster if you just jump and then move to the right
3) If you keep pressing M1, the shooting animation keeps playing, but no bullets come out. (Check out animation Event triggers to shoot gun every time the animation reaches a ceartain point)
4) You can ignore every enemy except the boss and the ones who shoot your friend, and after killing the boss the victory screen is too sudden, you should show that the boss dies before doing that.
5) You dont explain the controls (although you explain them in the game page, you should also leave either a tutorial or a "How to Play" inside your game)
Overall, you have great talent for art, graphics and audio, pretty impressive. Good Job :D
