Not marvelous, but not bad
Your game, is from a good plot, but I think you don't have enought dig in it. You should put other colors, other form, and other eplode from rocket. The same system is quite boring, as a real firework. Big circle is fun, but some are smaller, bigger, some red, blue... Why not put a colors combo too ? all red, or a red, blue, and white ? It's just some idea I think. Cause I think this game could be make for people who want to dream a little :)
Follow your work my friend, and good luck !
Its actually a fun game to play and the music is pretty good. Would be awesome if you got the combo higher than 6.
