For people wondering about the indie puzzle pack:
Tidalis is a lot of fun and the story mode has a sense of humor.
Droplitz was really challenging for me but it is still pretty fun. It seems well thought-out and you unlock levels by scoring a certain number of points on various levels.
I haven't gotten around to playing cogs yet
Shatter is, at the moment, my favorite game in the pack. It is similar to the old tile breaker game (I don't remember the exact name) but has a lot of extra features that make it fun to play.
Puzzle Dimension is a new and fun concept. The puzzles are challenging but not overwhelming.
I'd say I am very pleased with the pack, especially for the price of $5.
