First of all, the presentation of the website is fantastic. Simple but effective.
Now for the hard love part :) (it wont be too bad i promise)
You really need to add instructions "in game" for what we are supposed to be doing, there may be instructions on the website but I, "and most people" will be too lazy to look for them. I logged into the game, walked around for a few seconds, destroyed a couple blocks with mouse, then turned it off.
If i understand correctly you have a random generating environment, which is definately a plus, but it needs to be backed by some challenging gameplay.
You have a good start here, i would suggest really fleshing out the gameplay elements before you continue any more work on the website....
.....which im looking at again right now... and watching the video of the gameplay, (Im not going to delete my post) but i would take down the construct version until it is functioning. I would not want people to be testing my game in the state that yours is in, when you have actually gone so much further than this in another game engine.
The old one I have pretty much dumped, it's being remade here in C2. I am having it out for testing only so people can report bugs to me ;)
The website however was by my brother, I do not focus on that since I am not the designer of that.
I also have a music designer, and a graphics artist (which for right now I haven't implemented his gfx)
I made big mistakes with the other one, the least I can do is put it out for testing etc <img src="smileys/smiley36.gif" border="0" align="middle" /> <img src="smileys/smiley4.gif" border="0" align="middle" /> <img src="smileys/smiley17.gif" border="0" align="middle" />
