Excellent Challenge for a Simple Concept.
Like your other game, "Don't Push the Button," I admire this game for its focus on challenge rather than graphics. The puzzles themselves are relatively simple, with a few fun tricks thrown in that may trip some players up on their first few plays.
However, as with your other game, "Don't Push the Button," you neglected to mention the relative difficulty of this game for the limited amount of time given to complete the puzzles. As I mentioned in my other review, people prefer to know what they're getting into before playing!
The difficulty of the puzzles rises progressively, though once you've already solved them, the game simply becomes a test of how fast you can connect the dots. The first five puzzles do a good job of introducing the mechanics of the dots, allowing the player to understand the basics of the game before progressing to the more complex puzzles. The second set of five puzzles is where the real challenge is, as the player needs to solve puzzles with numerous dots on the screen with high values while saving time for the final set of puzzles. Thankfully, the last set of puzzles is a test of speed, considering that, by this time, only a few more seconds are remaining on the timer.
Despite what some may believe, this game IS BEATABLE! I myself have completed the game in 50 moves with 3 seconds remaining ( Though I must admit, it took quite a few tries ( ^_^ ) )
Overall, an excellent game; you just need to describe the challenge more clearly so that players may understand what they're getting into [Only one minute to complete 15 puzzles :O ].
I hope to see more of your work in the future!

@Delmlin: Puzzle 7 is not broken: you need to connect the "3" dots to the "2" dots first, which will leave a "1," "2," and a "1" dot. Then, you can connect the "1" dots to the "2," which should form the figure of the letter "M" (There are a couple other configurations, to be sure, but that's the standard figure for that puzzle).
