This is a pretty cool idea! I like that you were able to create a story and a changing environment around that story. I agree with some of the other players that the difficulty curve is a little rough; I wasn't able to even finish the "easy" mode because of the insane rate enemies spawn after the background changes the first time, but in all honesty, being on a laptop with a (pretty unresponsive) touchpad did not do me any favors. I was able to figure out the (really clever!) health on my second run, but at first I thought that was the clock's health and that the enemies were killing it (not me). Aside from that, though, this is a really fun entry and I like the clock idea. Great job!
