They have a bug and can't be completed or it's me doesn't found a way to complete them ???

I guess this is unintended, as it doesn't use the property of the 'sticky' block? https://www.youtube.com/watch?v=SggSAhZmsDo

限定公開したアップロード画像を見てほしいのですが、左上の氷ブロックを右方向に操作するときに、長押ししながら操作すると通常の挙動をしますが、クリック操作で氷ブロックを操作すると氷ブロックが異常な挙動を取って、移動マスの前でなぜか止まるという現象を発見しました。...

I see there's an achievement for clearing the extra level, but I cannot find any extra level. I finished all 80 levels, the block on the right of the last pack has the sunglasses on, clicking it displays the thanks message. I tried playing with the sliding piece on the main menu screen, but there's no hole to fill in, all I can do is move it around until it slides off the screen. Am I missing something?...

Hallos, wieviel Level hat dieses Spiel? Danke :)
