Nice concepts so far. The level with 50 or so spiders coming in from both sides is a bit much; might want to try a more creative way to help hide the buttons but flooding the screen with noise isn't doing it for me.
It would be nice if the text box cleared itself between answers or at least selected all the text so you weren't forced to delete your previous answer first. Also, needs some work on accepting alternate answers (i.e. accept both "underground" and "under ground"
Noticed an issue - after the super secret bonus level, the stars don't clear when you go to the next level, obscuring the screen until they all move off the side.
