The rooster's jigsaw puzzle did my head in. I had to come back to it a couple of times on a span of days to get it right. I don't know how I solved the next puzzle either! There were no clues that I could see.
I use Wick Editor for similar kind of games. I made a couple of small projects in it. I find it easier to work in. I'm currently working on a table-top game for two or more people.
