The game is a brilliant representative of the indie roguelite genre, targeted mostly at Binding of Isaac fans. It has plot, inventory management and fast-paced action.
I would especially point the nice cultural reference to the immortal Zero Wing by Toaplan... Or just particularly bad English.
Still, totally worth playing, assuming you have Windows PC, play with mouse and your resolution doesn't mess up game's UI.
