Multiple problems with UI
This looked promising, but two big problems ruin the experience. Once you place a piece, it is locked in and cannot be repositioned, even if it’s the wrong piece. And the puzzle solving window takes up only a small portion of the screen, with a wasted empty margin around it.
Bad mechanics of app
The app is not like other puzzle apps. It lets you lock pieces into the wrong slot instead of keeping them sliding. Cant move them to correct slot
