Copied from my own Backloggd entry: 

Absolutely phenomenal and hysterical shmup. Extremely kind, but never pulling punches. Nekotosakana is one of the most delightful shooting games I've ever played. Everything about it is deeply sincere without tipping into the self-serious or self-indulgent.  The keyboard control take on twin sticks has changed my perspective on the control scheme.  The game escalates nicely without being too overwhelming to a new shmup player or being dull to an experienced player. A behemoth of a game.
