### 4/5 — 3个建议和一个bug

*2026-01-19*

建议：1，如果判断错误，终止这一局时，建议“exit game”弹窗不要遮挡grids。
2，游戏结束时，应该现实正确的答案，或者至少显示输错的格子里应该正确的数字
3，格子很小，如果手指粗的话，有误触的可能，下面的数字可以定义为一排或者两排
bug是，在手机傍晚切换成暗黑模式时，棋盘多了错误的、显示突出的直线，极大的干扰，直接让人无法继续游戏。这是个严重的bug。

**Developer response:** Hello! Thank for the feedback. I will get this fixed in the next update, thank you.

### 5/5 — Only one bug I found

*2025-12-11*

I really like the app. Pretty simple, but nice looking. I like the notes portion and that it stays selected till you deselect. However if you put a wrong number, then hit back it erases all of your notes as well. Has been fun doing daily challenges and I like the different modes.

**Developer response:** Hi.

Thank you for your feedback. This bug was just fixed in version 1.2, which was released today. Update your app and enjoy Sudoku :)
