- The Tower is a defence game. You stack up defensive blocks and use spells 
   to protect your main heart block.
   I suggest normal difficulty first, if you find that too hard after a few goes trying 
   out different strategies maybe drop back to easy.
   Rich mode is just for mucking around at the start to build a tower however 
   you want. Only play this after you've played the game properly.
   General Tips -
 - Flying won't attack your heart if it's not in line with them, but will pose a \
     threat if you build high. So be careful.
  - Cannons work better the higher they are. There range & accuracy is based 
    on there height as you will see.
 - Try to use a bit of everything, don't stick to just defensive, or just offensive.
   You could call this game a "Tower Defence" but it really isn't at the same 
   time :P a little twist on the genre in a way you'll see :)
