I so wanted to like this. But The number entry pop-up covers part of the grid. You can only put in one number as a pencil mark, which is useless. With a tiny bit of work this could be great. Given the time that has passed since the last update, I’m not holding my breath.

The game is obviously functional, but the developer’s bizarre implementation of numerical entry makes it difficult to play. Tapping on any cell immediately displays two rows of numbers (1 for entries, the second for notes), but they’re displayed across the MIDDLE of the puzzle grid, effectively blocking the cells you’re trying to solve. Deleted after 5 minutes.
