Good game... but I don't understand how to get new cards. I got 10 about half way through... but then no more till the end. I thought the cards were based one experience? Then why am I not getting any more?
Addicting but only 3/5 because: built a bridge and had it almost work, added an element and had it fail, removed only the added element and the whole bridge still fails. Nothing has changed. Basically the physics are a little off.
