That spinning wheel was waaaaaay too slow. Also, the game quitting on me when I die, that's pretty rude! I was expecting to be taken back to a home menu.
As far as the theme is concerned, I feel there could be a better exploration of it. It was not apparent to me how the spinning wheel was integrated with the narrative or mechanics of the game.
I enjoyed fighting some robots before being finally overtaken by them. Sometimes I would swing at them, but it did not register a hit. I wonder if that is stat based.
The maze was merely a succession of identical rooms so the level design could be made more varied. There is a good visual base even though the graphics are a bit stiff.
I would give it another go if there were any improvements made.
Edit: one last thing. Because this is a game made in Unity, you should definitely make a Web build for it so people can play it in the browser.
