lol,love it
awesome game, i played it properly but that soon got boring (as most reviews have noted) so i messed around then, seeing what was the most disgraceful structure i could possibly conceive. i ended up making a structure that fell without any joint breaking,a structure that resembled a ball of satanic symbols (a bunch of reinforced pentagons) and a pathetic tower that i just wanted to break, but for some reason couldn't, which confuzzled me.
i think that when you make the sequel you should make the "free mode" be completely free, make breaks and falls do nothing, just keep it going (to reduce lag make fallen pipes disapear after a few seconds), which would keep easily amused people such as myself amused for ages.
i also have an idea that might be good for a challenge. have objects fall from the sky and hit the tower, putting pressure on the joints.
then put an option on free mode where you can throw abjects at the tower yourself (so i can have more carnage).
and have different types of pipes, some stronger than others and some having longer reach. maybe weaknesses in the pipes, like having a pipe that holds allot of weight but the objects(if you use the idea about the objects) stick to it, causing weight to build up.
well, thats about it, thanks for the game.
