Good gets quite addictive and as Backflipair said good use of action script
this is so cool
i made a house with this.(okay i know that's kinda of lame but the game is cool)I like making 3-D shapes!
but instead of having to keep clicking 'delete point" or "bar", it should be kind of "stuck" onto that setting so every time you clicked on two points after selecting "create bar" it will make a bar, instead of making a bar, then having to click on "make bar" again and again...... :S...... but anyway still good.
Fun little toy.
The only "bad" things are the nasty UI and the tiny-tiny help screen. Not really important but *shrug*.
Also there are some minor glitches with the vectors with bars (it may be my machine though).
I suggest adding "world" gravity in a next revision.
Possibly even "entity" gravity (e.i. have a ball attract other ball).
You could build this into a nice little puzzle game.
See look up Enigma and/or Oxyd and the Incredible Machine.
A very well done game. Like you said, a time consumer. I look forward to seeing more of work like this.
