This game was a great idea for the theme. It really makes the theme a core mechanic to the game. I liked the game I experienced when it worked so I think it would be good with some fixes.
I played in the browser so I don't know if that was the cause for some of these issues or not but here are some of the problems I had with the game. For some reason I could only get the game to measure the height of my character a couple of times. All the other time the character just disappears and you are left with a bunch of uncleared blocks. When this happens it also gives back points to get more blocks which allows the player to continue placing blocks until they crash the game. You can also crash the game within the point limit if you build mostly using pillars.
I would have also liked if you could pick the player and blocks back up when building so you don't have to restart if you miss drop one thing. On the UI side of things, I think the buttons should be on the side since the goal is to build up as high as you can the buttons start getting in the way when placing blocks.
I feel like I was a bit critical in my review but I think this game had a good idea. I just struggled to get it working a lot of the time.
