well thát is a nice game
its worth a 10 theres no doubt about it, but i have som tips for a sequel:
More parts, witch you can unlock by reaching a height, like you start with wood, followed by steel etc.
Of course a sandbox mode...
And some special missions, like finishing buildings in time, and make or finish sculptures within specified lines.
I like this game very much, and i hope the sequel will be even better
