While it becomes difficult after a while, you do certainly have a very playable game that is a nice layout and quite addictive. Perhaps you could use some sound effects when you complete the words that you've completed.
I like it, but the additional powers are granted so quickly after the completion of level one, that it could have used being phased in over a longer amount of time, to let the player keep up with the pace of it all.
Still two nice game modes, a nice piece of ambient music and a background which is quite calming. Great stuff :)
