Not too good
It had it´s good parts, it had it´s bad parts. One of the good parts was that you could click on things to bring them in front, I liked that. And there were plenty of objects, weapons, body parts and other stuff to use which is also a plus. It was also really good that it had a "Sound OFF" button, cause the music was pretty repetive.
As for the bad parts: Even though the clicking on items to bring them in front was good, there was a problem with this. That is that you bring them in front of the title screen as well when you go back. Speaking of the title screen, that could use some improvement too if you ask me, it looked a bit ugly and empty. But the most important bad thing was the lagging. That was really annoying, you should try to get rid of it cause it does ruin the game (like Imacow already said). Even starting the game took a few seconds.
Overall 4 out of 10, 2 out of 5. Not the most original idea for a game as there are plenty of these already. And most of them were better ones, but I see this is one of your first flashes ever so it´s okay. Good luck if you´re gonna make more.
