Such a great danmaku action game with detailed pixel art and animation. Everyone looks alive and interactive -- when you hammer them they actually bounce like a spring. Writings are also reflecting the characters and their respective Nordic lore with humors.
Enemies' patterns are simple yet challenging. There aren't that many bullets but you will need to carefully plan your positions after Wakasagi and it does require some accuracy.
Although there's no music, sound effects fit the combat very well and I actually don't think it even needs music to be good.
