Update
Added new boss enemies! The Slug or the Snail will be the last enemy of the round.
More bosses coming later!

Changed layout of tower information display.

Towers that are not affordable will have a transparent button.

Animated the flag and grass to appear as if wind is blowing.

Edited tower images to remove grass layer and now draw tower on top of empty grass tile.

Changed layout and look of some levels.
Added a new snowy level, as well as a desert level.

Now you can destroy an object on the map with the shovel, but it will cost 20 coins.

Slowed down the spider just a little bit.

Updated credits.

Changed the process to unlock tower, now you need to unlock the towers in order.  However, this will not affect your previous save data, so you will still have the towers you have unlocked if you played a previous version of the game.
