I like the game, I'd just like to see some kind of tutorial or written explanation of what does what. The basic concept of clicking symbols and having them appear at the bottom is easy enough. It took me some time to understand that I only need three of a kind in the bottom bar and that they don't have to be right next to eachother. Also, I'd like to see an explanation of the power-ups. The only way to know what they actually do is by using them, which isn't the best.
Keep it up and continue making great games like this!
