Slitherlink Mastery

The first puzzle I ever did was a 20x20 pro hexagon grid. This was admittedly a mistake as I was a newb and mistakes were made, slowing down the process considerably. It took 10 hours, but I was really proud of myself for fixing all my mistakes and finishing. I didn’t realize the puzzle would just disappear once I was done, so I went to the main menu and now this thing that I spent 10+ hours on is just gone. This is incredibly upsetting. Honestly, I’m a software engineer and in not too much longer than the time it took, I could code my own slitherlink app, which makes the value of this one pretty low to me, definitely negative if I plan to use it to solve another large puzzle. I wish I had paid more attention to the rough corners before using this app. Also bad for colorblind people. I’m colorblind and it really was impossible to tell red vs green numbers. I had to count the walls for each cell. Also errant touches would trigger false walls I didn’t mean to tap while I was planning around and there were a few puzzles that were ambiguous (more than 1 solution).

A couple suggestions: Add an option to automatically X out lines that should obviously be X’d (like when I put a line next to a 1, X out the rest of the edges.) It’s hard to tell when the puzzle is scrolled out to the side sometimes, so I end up playing like I’m on the edge. Some indicator (some blurring?) showing were not at the edge would be nice.
