For a semi-beginner, this is a really good start! Unity is difficult, even more so when you try to make a game in 48 hours alone. You did really well with some pretty cool art and a nice setup for a game. I would love to see more of this game! One tip is to make the export a little smaller, since I couldn't get it to fit onto my screen, even when I pressed fullscreen. I suspect the latter part might be an issue with the way Unity works with canvases and screen scaling, since the button disappeared. 

Its quite short but it seems like it would have a deeper storyline, great start!

Nicely done! Don't feel discouraged, practice makes perfect :) Also, 48 hours for making a game is quite extreme so congrats on getting through. It only gets easier from here!

Great start, keep at it!

The level design and controls are very intuitive. Love the art too! I messed around a bit and managed to soft lock myself by killing the guard off screen. I can't pick up the body, presumably it is too far away.
