Quick fix

This is a quick update to fix an error that some people have been getting at the game launch. Basically, if you launch the game while RPG maker XP is not installed on your computer, you get an error. But now I've made sure to test it after uninstalling RPG Maker, so this new version should work for everyone! I'm sorry to those who couldn't play the game.

- I've also updated a the princess' human sprite, and Zepherion's "nude" sprite, to make the art look a little nicer.

- I've placed the NPC that gives you 5 potions closer to the mouth of the cave, since I felt like it was easy to miss her.

- Fixed a few typos
