OK this is the last time the game is going to change in any big way! I am basically totally happy with this build and I hope you are too.
Zen of Sudoku - Massive interface simplification and improvement (link) - Removed "Advanced Mode" as it is no longer needed. - Added "Show Dupes" again in place of "Advanced Mode" - Big improvements to the Hint/Explain system to make much more clear (esp. in regard to advanced pencil mark strategies) - You can now press spacebar to have game place all pencil marks for you - Improved solve row/col/box tile particle effect feedback - Improved game help and pacing tooltips - Improved tutorial to teach more about Sudoku - Fixed bug with Eternal Stillness and High Road not being given at the right times - Many graphical improvements (ships on main menu, crane, flitting butterflies, weather effects, particle drawing, etc.)
Please leave your feedback, as it's not too late for me to change things if they are really problematic!
