It was ok
To say you are 13, the game was alright.
First off, the graphics DID suck, which I am sure you are well aware of, but at least the graphics resembled what they were meant to, also the hotel/house looked pretty sweet, you did a good job on that.
The coding was pretty simple, but you pulled it off well, you gave everything, a choice of weopons... the pre-loader game was a nice touch but there were only a few enemies, next time maybe make a random spawn code which shouldn't be too difficult as long as you set some _x and _y spawn points so nothing messes up there.
The sounds were good, not bad quality and always played at the right moment so not much fault here, but a good background song would be a nice touch but make sure it fits the genre well or you could look a fool, something slightly... rocky.. but not too harsh or loud and without lyrics, check the audio portal.
Violence, well it was only held back by the graphics, I loved the alien creature things falling out of the windows, that was sweet and a great touch.
Humour was a none, which is a good thing because it wasn't a comedy :D
So, I suggest you should make another 'Grave' game but make it a little longer and better graphics. I suggest you should get someone else to help so they can do the graphics or help with someone else, whatever... I know I'd love to help, if you want to get in touch contact me at deadsim2[@]gmail[.]com :)
Keep it up - 3/5
