I thought it was outstanding, for what it was (extremely short). Beautiful, hand drawn (literally, hand drawn, painted and cut out card stock filmed in stop-motion a la "Claymation") graphics, soothing zen-like music and atmosphere, wonderful gameplay, nicely challenging puzzles and a lovely minimal story.
I suppose it would have only taken me an hour to play if I hadn't totally missed one of the clues (found it, but I couldn't figure out how to use it, or if it even WAS a clue) and spent 2 days, on and off, trying to figure out how to solve one of the puzzles.
As it was, I managed to ferret out the answer I needed from things that the developer hadn't intended, LOL. After I finished the game, I found someone had posted the correct clue and boy, howdy did I feel as dumb as a post for missing it.
Bottom line? This would have deserved 5 stars if it hadn't been for the shortness of the game...shorter than the free Samorost 1. In fact, as the first part of this apparent longer series, I think this should have been free, given its lack of content. Because of that I only gave it 3 stars. Great production values, challenging gameplay, beautiful artwork and lovely music are all 5 star worthy. Length of game is only 2 stars.
I'm now gun-shy of getting the subsequent parts for fear they'll be just as short. We'll see. Next time, I'm going to wait until others report back on length before I shell out my money. I may even wait until all parts are released and see if there's a full version. If they end up being 5 one-hour games, for $7.49 a pop, I won't touch them.
