Such a deep story with so much character development (:
You have very little time to react when moving(up or down) towards the enemy, so maybe zooming out or making camera move faster after the player might help. Well done anyway!

I like the Cutscene in the beginning, I hope the story is not based on a real story :D
Sounds and Music would add a lot. It is hard to fight to the left side, because if you don't press the key, it resets instantly to the right side.
Keep up the work.

So apperantly my comment wasn't saved, so I try my best to recover it:

First of all I like your game, it was short but fun! Also the story was hilarious but I think some people would find this a little bit offensive (like the wife that always complain about anything). I think with some voice effects and sound effects it would make the cutscene funnier xD I encountered a bug of collision, I'm not a Unity expert but it seems to be the type of colliders (f.e. "Continous" or "Interpolate"), my tip would be to do a research about the 2D colliders. Also I liked the artstyle and the environment! I think saving the rotation of the player even he is standing would be great (so after you ran to the left side he stills looks at he left side and don't turn back), so you have the weapon in front of you. Keep it up and I would like to see your future updates!

Your game looks really good.
