Its a good demo a bit short but at was fun i like the half 2d half 3d of it.  But i dont get the point of the 2nd roket you get you dont get anymore science then the first one it doesnt go much higher or anything.  and it could use something at the end telling you that you are done with the demo. 

ill tweak the 2nd rocket next update if blockdogcat finaly gives me a break but ty for the review
