There is one skill needed to complete game. To place pieces fast. That's why there is possible only one base of badges - combo badges. Like make 40 combo. It's very hard for me but not impossible. Because there is only 2 ways to do it: 1 in 6x8 mode not place only 8 pieces in combo or in 8x10 mode place half pieces in combo.
About bug with last piece. We thinks that today we fix it. Thanks for your opinions. About badges - we try to implement them.
Have a good time with this game:)
