I also had the sudden crash. It occured when there was Oil on the screen and perhaps it was going to chain merge into something bigger all at once, or...
Maybe something collided with two objects at once. It's a recurring theme in suika-like games that you can have multiple pieces touch at the same time and cause some sort of effect.
I like the shapes and physics, but yeah. Just revamping a game from a year ago isn't going to get much attention now the suika craze has kinda blown over. Does make is more obvious what the game is with the title though.
Sure is a lot of Sukia on this page ...
oh, by the way, a volume control would be nice rather than just a full on mute/unmute.
