Gem Worlds v0.4.0 Demo, with proper MacOS support

Hi all,

I released a new version of the Gem Worlds demo a few minutes ago. This includes a few changes:

• The MacOS version now launches correctly

• You can pause or quit the game to the skill shop at any time, then resume from the same level. I hope this change will encourage more players to buy and try different skills.

• Fixed a crash in the options menu

• Made it clearer what area explosions affect

• Fixed a bug where picking up an item wouldn't show it in your inventory, if you already had that item, but used up all of it from your inventory.

• Space out treasure chests a bit farther from each other

• Prevent freezing on level generation if there's no space for treasure chests

• Fix: item audio doesn't play when you use the last one from your inventory

• Fix: in some cases, you can see multiple buttons for the same item

Please let me know your feedback, especially around the skills changes; did you try others? Why or why not? Which ones did you like?
