Jeez, how many people don't listen? A player market would make multi-accounters nigh on invincible. You could have 5+ accounts all being merged into one super account via trader.
Noooooooooooo!!! Every time I play this game I get really far (Level 240 today alone) and then the file hasn't saved when I go back on!! Even when I manually save it it's too confusing for my piddly brain...)=
Fantastic game but I despair...
I thought it was cool how I found myself using real world bridge designs - one of the levels looked just like the Golden Gate bridge! Upright steel supported by ropes works well and is a very cheap method.
