Updated to version 0.2:

• Added new levels.
• A new shortcut to place marks, you can press keyboard 1-6 to place marks when your mouse it on empty cell.
• Removed skins and moved to option as "Dark Theme" option. (I might add it back later when I have time to focus on this feature.)
• Rich discord presence.

I will update Web demo later, for now you can download it to play on your PC. :)
