There were a few things that were broken and needed fixing, so here's a patch for that.

Additions
*Stone and Wood now have variations
*Added a "Cursor Transparency" option to the settings
     *When disabled, stops the cursor from changing transparency

Changes
*The landmine limit in debug mode has been upped from 10 to 15
*The Deep Mines now take on a more red color for better contrast
*Updated the hotbar sprite for landmines
*Updated the leaderboard API and project settings
     *This will either lead to a better experience or break everything
*The Enter key can now be used to make selections in menus
*The game will now use GLES2 if GLES3 is unavailable
*Improved the particles that blocks emit

Fixes
*Fixed a bug where the block count won't be reset
*Fixed a crash that occurred when placing a landmine in debug mode
*Fixed a bug where infinite landmines could be placed in debug mode

*Despite all these fixes, landmines are still incredibly buggy when used in debug mode
