For a while, I've been thinking about writing a game to help lock in the nasty parts of language learning (is that new german noun male or female? what case does that ending mean again?) which would capture the unholy compulsiveness of diablo2 and snood. I'm certainly not there yet.
But, here's the demo:
Match nouns with their cases, to score points, and clear them from the screen. Get multiple words in a row right, to activate the hint button or (not available yet) other special powers. As you work, new words will fall, and the game ends when they reach the top of the screen. Move to a harder level, by completely clearing the screen. How long can you last?
