Updated to 0.1.2

Hello, reapers!

Thank you for playing and commenting on the game.  I added some features based on your feedback.

[v0.1.2]

• Added auto-attack option.
• Added WASD move.
• Sound effects no longer overlap without limits.
• To avoid having text files swapped to Japanese on load, the game no longer auto-saves by blue NPC.
• Explosive Effects can no longer get souls from Fire tiles.
• Fixed an issue where the first tip would disappear immediately.
• Fixed audio file not found error.
• Fixed an error that caused some effects to go off-map.
