I really really want to play this puzzle game, it looks fun. But...did you forget to mention a rule or something? Because at most i can play a few x's at the beginning and then...nothing. I just can't figure out how to solve a single one of these puzzles(at the easiest level), heck, to even place a single dot.
Even though i am usually VERY good at logical puzzles like these.
At most i think one has to guess and simply do "Let's try this and see how far i can go" which is the worst thing one can do in a puzzle.

I hope you simply forget to mention a rule or something. Something like "two dots can't be neighbors" or such

Also a "go back to main menu" button would be nice

[EDIT] Due to the correction in the description, it's much better now. Changed score from half a star to four
