### 1/5 — My puzzle disappeared after I finished. 10+ hours of work gone

*2020-12-16*

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).

### 4/5 — Pretty good, could be great

*2020-06-08*

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.

### 4/5 — Hostile to color blind people

*2019-10-19*

The game is really nice and clear. Except the color schemes are really difficult to read for color blind people.

### 4/5 — Hard to see

*2018-10-18*

Great game, wish they had different color scheme cause I’m color blind with the colors they use so it’s hard to tell which ones are wrong

### 5/5 — Nicely done

*2020-05-27*

I was very impressed with this game.  Zen like themes.  Good range of challenges.  No annoying ads!  Happy to pay the 3$ to unlock all the levels.  Thank you.
