Just like a fun children's book - though still fun for all ages. Super relaxing.
The puzzles were difficult enough to keep me interested and although I normally don't want to go near click and point games, I overcame that fear within a couple of minutes. I also enjoyed the lack of instruction and the intuitive nature of the game. The music is nice too and the wordless story is fun to follow. I've noticed complaints about the lack of story, but I feel Tiny Bang Story, despite including the word 'story' in its title is very much in the same vain as the children books that conjure in mind. Perhaps they should have omitted the word from the title.
The game only lasted me 3-4 hours which was a good amount of time to enjoy it on a Sunday morning. Highly recommended as a break from action oriented games.
Criticisms
1) completion of one or two puzzles were more up to luck then logic.
2) low resolution... not that it really matters. just see it as missed opportunity to allow far higher resolution.
