Quick fixes

Thank you all for the amazing feedback! In a short time I came up with some ideas to make the start a bit more forgiving and also fixed some quick small issues along the way.

The full changelog:

• The map floor is now darker so the walls are easier to see in a glance.
• Magic Potion and Arcane Potion are way cheaper than before, being more in line with the other consumable prices
• Shopkeeper now asks you to talk more to her, hopefully leaning players towards talking to NPCs multiple times without the need for trial and error
• The RTP is still included with  the 1.0.1, but its not pre-installed anymore as a lot of weird sound effect glitches started happened after the pre-install
• The main game final boss now disappears properly after you defeat her once

Remember, if you already started playing the 1.0, you can continue your progress by copying your "Save01 (02, 03...).rvdata2" files to the new 1.0.1 folder.
