Having the sprite change colour as the card approaches the right position is an interesting idea, but the idea of these minigames is that it should be pretty obvious what you need to do. Perhaps if difficulty can be configured we could use that though for easy setting, although in that case I'd argue against using red for good, since in my culture at least red is usually used for warning (as well as these days, charging also). How about red if its misaligned, going to green as it gets closer to being right (although in practice I reckon it should actually go red to grey, then grey to green, since if you go directly between red and green you hit brown at some point otherwise)
