Demo update

Hi everyone,

I listened to your feedback and fixed the most important issues.

• Added popup message on how to buy units to make it more clear.
• QOL: you can now right click on items to pick them up or towns to enter them, if they're within range.
• Fixed an issue where worldmap tooltips would stay open after an item pickup.
• Fixed quiet sound effects and other related sound issues.
• Fixed rare bug where stationary guards would chase you.
• Fixed bug where you could trigger a roaming monster at the start the game.
• Many minor tweaks and fixes.

If you have any issues or feedback, you can report them in the Discord: https://discord.gg/B9qtzAFKW3
There's also a send feedback button in the game settings menu.

Have fun.
