Marginally okay.
First, with the good. The game looked pretty darn good, nice environments and all, if a little bit on the strange side.
Other than that, I wasn't particularly entertained. A pretty simple point and click puzzle, but a bit counterintuitive. The piece of wood that I had to use to get the batteries I got by randomly clicking around the bed hoping that my idiot character would push it out of the way, there's no real indication of what to do there, unless your hope was for the player to get frustrated and randomly mouse-flail until he hit something.
After the first random flailing, I figured that it must be something else like that to continue, so that's how I found the key. I jsut started randomly clicking on everything. There needs to be some indication of what you're supposed to do, instead of just being stuck clicking everything around. Maybe there were cracks there that were supposed to be an indication, but I couldn't see them due to the darkness.
There's nothing to really connect you to the character. The game is really short, too short to make a connection, and he doesn't have much of a personality other than being too stupid to get some batteries from under the bed without a stick to reach it, and refuses to carry a rifle around because it's too heavy for him to carry around. If there was more connection to the character, the Night of the Living Dead (aka Rocks fall, everybody dies) ending might make a little more sense, as is it's just kinda... random.
So, make the puzzles a little more intuitive. That isn't to say easier, but there needs to be some indication of what's required. Possible control over the light while you're searching around might make things easier to find, like the place to break the desk for the key. And as few items as you had, a bar with them listed across it instead of having to click back and forth between a backpack might have been in order, because 3 trips to the backpack to put batteries in a radio was a little annoying.
