For a game with somewhat real physics, its not that bad, for a start. I notice many problems, though. First off, ads everywhere making it very frustrating to play as it requires focus, and constant disruptive ads do not permit focus. Second, there's not enough parts for a car, or much of anything honestly. the only thing i managed to make was a mobile home, and had nothing to move it because when i tried to make a car, it failed worse than a Korean missile test, going allover the map and trying to fall apart, the poor thing just wanted to stop suffering, but it couldn't even loose a wheel even though the wheels kept going 5 feet from it and then somehow reattaching, the controler is its only saving grace. Thrid, when i made this mobile home, i made it from the inside, and fit perfectly fine in it. I go out, and try to go back in, only to be stuck out of it because i don't fit. I'd expect, if i fit before, i should fit again logically.

It's a great game but could use some improvements such as the lack of a two-way control for bearings and the inability to connect/ disconnect blocks. Could you add a valve( I can't think of the right word but it basically is a valve but for turning something, not like a cut off valve) and a tool that lets you select which block you want to connect/disconnect. Those 2 things would vastly improve the game( in my opinion....) Could you consider adding that?
