Post your playable Crush the Castle 2 maps. There are other threads for talking about CtC2. If it's not good for shooting at or interesting to look at don't put it here: NO castles that fall apart by themselves, NO random junk piles.
I liked the physics of the first two CTC's albeit, you can make some interesting structures in the latest game but the physics suck wind.
You need to adapt and use new tricks to keep everything from falling apart. I use the foundation blocks a lot to hold my castles together. My ships were getting stable until lately when I started pushing the limits again.
