I could see this as a good game in the future. just put shift as a running button and have the ability to place block and make your torso not take up half the screen and from there its a pretty good start. I couldn't do what you did.
I would love to see this on steam greenlight. you should put it on ounce you get this game going. hopefully it will be F2P. If you do, can you put my name on it soewhere?
