I failed to make a devlog for version 3.0 when I first published it, so this devlog will be a simplified explanation including both the changes made in version 3.0, as well as further changes made in version 3.1.

Version 3.0

• Episode 3 is now available to play. Episode 3 features new obstacles and a new boss battle.
• A new game mode was added called the long haul. See how many levels you can complete before you lose.
• Bonus game modifiers to change the types of mines that appear in the bonus games.
• A new level select mode, where you can play levels from the adventure mode.
• A brand new level editor where you can make your own minesweeper levels.
• Ability to import a custom minesweeper.
• Other gameplay improvements.

Version 3.1

• Added triple mine functionality for Free Play mode.
• The game now remembers the last tile you flagged. When double/triple mines are enabled, pressing the 0, 1, 2, or 3 keys will change the flag quantity on that tile, and when antimines are enabled, pressing the '-' or '`' keys will change the flag's polarity.
• Togglable command wheel in the settings.
• Ability to preset mines in the level editor.
• Ability to import custom music into the game.
• More custom stages can be saved.
• Other gameplay improvements.
• Fixes some bugs that version 3.0 had.

Version 3.1.1 fixes many bugs that version 3.1 had.
