I can't get over how cool this is. It's extremely polished, with great dialogue, a wicked soundtrack, a good-looking pixel-art style, challenging danmaku patterns and an amazing overall concept. It's about as perfect a winter Jam game as is possible.
I hate that I have a skill issue with keyboards (I much prefer controllers), so it'll take awhile to see the game in its entirety, but man, it's so incredibly good. Five stars.
