This is a great app for playdate! I do have one piece of feedback: the crank to select letters is too sensitive. I have to very carefully go back and forth to arrive at the right letter, and sometimes my crank moves on its own while I’m navigating the puzzle, causing erroneous letters entered.
Would it be possible to use the system keyboard instead, such that I can enter words, backspace, etc. with it and then press okay? E.g. I press A on a Down entry, then the system keyboard pops open, and starting always from the start of that Down entry, I can use the system keyboard to enter the entire entry.
I would expect the big difficulty would be clues which span the entire screen or clues to the far right, since the system keyboard takes up the right hand side of the screen. Shifting the entire board to the left such as to keep the current selected grid cell always visible might solve this.
In addition, the standard playdate UX is to be able to scroll lists (especially long ones) with the crank. It would be nice to have this for the Puzzles list because it can get quite long, and pressing the D-pad down so many times in a row can get tiring.
Do you have any interest in releasing the source code? I would be more than happy to implement these features.
