Good puzzles. Was never too complicated that we got incessantly stuck, but tough enough that the problem solving experience was enjoyable. The voice acting and sound design isn't the greatest, nor is the story, but it barely registers for most of the game so it's an irrelevant point when judging the game for it's most engaging qualities. Can't say the price matches the amount of content present, but it's a really indie studio and they did pretty well.

really cool puzzles

Wonderful game. My friend and I played it from opposite sides of the world and had a great time communicating clues and solving the puzzles. The puzzles are unique and require some thinking.
Hope to see more from the developer.
