Post-launch improvements (v1.0.2 patch notes)

I've spent some time improving the game. Here are the most recent patch notes:

• Added launch options on Windows and Linux. Players had reported issues with the Nvidia OpenGL driver, so now you can change to a different rendering engine. There is no universally correct choice, so if one doesn't work for you, please try the other.

• Fixed a bug where achievements earned during the demo weren't saved to the save file, so they wouldn't be granted upon loading the full game. This is why more players have an achievement for beating the second elite monster than they do for beating the first one. 😅

• Fewer customers will now desire an item at any given time. It used to be a maximum of 4 in Story Mode; now it's 2. This should result in items selling more quickly, which may make the game slightly shorter, so I'll have to keep an eye on this. The rationale behind this change is that players generally wanted more battle windows to be able to earn different loot.

• Changed the currency symbol for French and Spanish from an "O" (for "or" and "oro") to a "$" so that players don't think that currency amounts are 10x what they actually are.

• Added a sheet-music button to the title screen so that players can find this on their own. Note: I only have English strings for this button so far; sorry, everyone.

• The lever is now highlighted when you first buy the Extractor Training perk. There was already a hand pointing at the lever, but some players thought it was pointing at the extractor itself.

• Fixed other minor bugs not worth detailing.

If you find any other bugs, feel free to post them in the discussion forums or on Discord.

Have fun playing!
