When I try to play the game there is only 1 tile on the floor

when i start my first run,after cutscene screen goes all black and i can't do anything

敵を範囲外の通常攻撃で撃破する、ってどうやって達成できるのでしょうか？ このゲームを何周もしていますが、この条件だけ未だに達成できていません。 How can I achieve the goal of destroying enemies with out-of-range normal attacks? I've been playing this game for a few rounds now, but I still haven't achieved this condition....

タイトル通りです Title

So it starts at the beginning, then I had the one tile problem. After 2-3 times i tried to reboot the game, it stops at the unity screen and close. Hope for a fix!
