this is a really nice game, i played to level 22 before realizing how absorbed i had become. the people that say it's lame either aren't actually playing it or are a little 'lame' themselves.
i think that the people who are complaining about adding to ten are missing the point. this game reminds me of an "arcade solitare" variant where you have to pick cards that add to 11. i, for one, welcome our new base-10 overlords. nice game.
i agree that this shows potential -- neat concept, decent physics -- it all might move a tad too fast but that aside I'd say you're off to a grand start.
nice animation style, hit detection is a bit off -- pegs will go right through the edges of the coins. a little lacking in variety but overall a good start.
