Nice it's good and beautiful game. How long did you complete them ALL?
Steam says 4,4 hours. But this is a game that is convenient to leave it opened and go to make a cup of tea, so I think a little less.
Do not understand me wrong, it is a good game, it is doing what is needed - it entertain and relaxes, but it has one problem: it is too easy for me.
Once upon a time, I was very interested (fond?) in picross, we called them "japanese crosswords", and I found one magazine for myself (then everything was on paper!), which had quite clear rules:
- there should be no completely empty rows;
- there should be no fully drawn rows;
- there should be no rows with no alternative solutions (sounds bad, try to explain: if you have numbers 1 and 8, and on the row of only ten cells, then it is sketched in only one way, but if you have 1 and 7 on the same row, then you need to think);
- there should be no symmetrical images;
- well, as a bonus, it was all classic black and white picrosses, so the images had to be similar to something, and not like four pixels in a row of green pixels - is a cucumber. Yay.
And with these rules, each new page was a new interesting challenge, the options of each next step had to be literally calculated (angles, and sometimes all the first/last lines can actually be quite often calculated by analyzing the neighboring rows).
So you know, if you have already finished thirty puzzles, how everything is done here. Opened / drew / closed.
