Really sorry for a low rating but I have played these type of games before and this one is pretty glitchy but I guess you already knew that. ALso I would suggest getting an NG preloader to use this game as well so we can all skip the annoying ads.
The gameplay seems similar to Bejeweled except for some reason the bombs are unclickable and you only need a chain of one to move on which is not right either since it should always be in pairs of three or more. Also there should never be a default chain of three or higher.
If it does happen then the game should have some coding to recognize it and automatically remove them for you instead of the player clicking on them. Another thing is you may wish to look at adding the ability to slide the blocks over by one to make it better.
Fix up the glitches and the game should be a lot better.
