Absolutely love the game - I think the areas I could see it benefitting is a bit more clarity on buildable area on the initial cylinder would be nice along with seeing what you can do to make it more clear where to move your mouse to get it to move in the direction you want since it becomes a little difficult in 3d to get it placed where you want. Also is there a way to rotate the blocks as well? I would love that feature too, though I can totally see not having it to further constrain the play space as well. Those are all just nitpicks though, it is great overall.
