CAD as a game. Free build the solutions to Lego puzzles, with a goofy plot to keep things moving and the same kinds of gadgets found in the classic Lego games for navigating the world.

I liked the general concept, but there were a few issues with execution that got in the way of it being a great experience:
* The build interface was awkward. For example, if you highlight a piece and then rotate your perspective, you lose the highlighting. This makes it hard to get things to land in the right place. You also can't group or multiselect, which means you can't experiment on the side or move all the pieces in a wall one space left.
* For building, all pieces have a clear idea of up and you can only join them according to that grid. So much opportunity to foster creativity lost. The holes in the side of Technic pieces are just aesthetic.
* No ability to control camera angle when you are running around sometimes makes it a pain to explore. You can pause to look at everything from a God's eye view, but that definitely breaks immersion.

Close but no cigar.

Appears to be a fairly cute game however it seems to fail a bit when it comes to the "Building" aspects of the game. Within the first 30 minutes of play (which is all I needed to play before deciding to refund) there were some very simple "place the blocks where they should go" puzzles followed up by several simple bridge/stair building puzzles.

What really struck me wrong was the fact that these puzzles weren't... how to explain... They weren't logical. For example, in the real world you can very easily build a bridge with 6x2 flats and tie them together with a few 4x2 flats under them. When you try that in this game, the bridge fails as if there's no tension force holding the bricks together. Then a couple builds later you can hang a bridge off some 1x1 railing parts that would have less tension force (in reality) than the flat bridge from earlier. It makes no logical sense!

At any rate, I came to the quick realisation that this game is pretty much a walking simulator where you'll go through a fairly silly story as you move from quick puzzle to quick puzzle. Each puzzle you do you're severely limited in creativity as they only give you a certain smattering of parts. Only AFTER you complete the build with the parts they want you to use can you go back and actually be creative with the build. Why bother though? You've already beat the puzzle and can move on with the story.

While I can see this game being fun for some, specifically kids in the 8-14 year old range, the fairly bleh story (which I tried as much as possible to skip through) mixed with the limited building options means I really didn't find the game as enjoyable as I was hoping. I absolutely love building blocks and crafting games, but this game failed to meet my expectations in a big way.
