Ver 0.2.0

• Add Desert region.
• Added [Head Shot] function.
  Attacking the enemy's head can do more damage.
• Fix explosion bug.
• Fixed a bug where Upgrade Stone could not be purchased.

To make adding fields a little quicker, I stopped creating scenarios.
I am aware of the lack of sound effects and the problems of normal monster combat.
I will complete all field additions and reinforce the whole.

The update at the end of December is scheduled to add a fourth region and gamepad support.

I am sorry that the update is later than expected.
Thank you.
