Castle Constructor Alpha 2.2

Castle Constructor Alpha 2.2 has been released. This update brings a requested feature and a new section to the game.

First up we have added the ability to undo the last placed section! Now if you make a mistake in what block or where you wanted to place it you can either click the undo button or press the 'z' key to undo it and get the card back. This can only be used on the most recent block and can't be used during a wave.

The other big addition is the new card, the treadwheel crane. This section allows you to pick up and return to your hand any one block on the map. There are a few limitations however. Treadwheel cranes gets a 'charge' at the end of each wave which will be indicated by the crane moving around. Clicking the section's activation button will activate the pickup tool after which you can click on any section (Other than a treadwheel crane) and it will return the block to your hand. There are a couple of ways this can be quite useful. You can use them to move some of your defenses around, taking a section from a well defended area and moving it to a weaker one. Or maybe you have an important section but its now inactive because the blocks under it have been destroyed. With a treadwheel crane you can now pick that section up and move it to a position where it will work. Yet another use is when you get a new pack of cards but don't have a good spot to put your new sections, this will let you move something out of the way. 

The rest of the change log is below. 

• Added the ability to undo placing a section.
• Added the treadwheel crane section.
• Added a new crane card pack which includes the new section.
• Improved the hard to allow for more cards. There are now buttons to scroll though the different cards if you manage to get more than can be held in a single hand.
• Fixed flags both not showing at all in some cases as well as changing size when rotating around the map. 
• Reduced the number of stone walls in packs as players would get way to many.
• Fixed blocks not updating their look when an adjacent block was destroyed.
