I was having a lot of fun sliding around on the lego surface, it was always something I did not enjoy with real lego blocks and this game gave me a chance to enjoy something I've always wanted to with them lol
I was a little lost for a minute because I thought I was supposed to be driving on the roads at first. Then I figured out how to add the extra lego bits to my main piece and accidently ran into one of the enemies as soon as I finished.
I think having just 1 or maybe even two currencies (offensive/defensive types) and add an extra lego pieces to the add-ons could create more choice for the player; I pretty much always made the same tank each playthrough. I don't think I was very good at it though or the game might be a little hard for newbies to start out so maybe giving a tutorial mode first just to get the hang of it and destroy some weaker tank lego would help players like me some more.
Really liked looking at it though, really did capture the feeling of playing with Lego again!
