Very hard but in a fun way. Does not overstay its welcome. Final boss is hard but I don't know if it's in the way it was intended to be. The audio design is ok, but the music is not, I would've rather it didn't have any music than what it had.
Game was fun and had a strong comedic sense. Gameplay was responsive except for shooting, which is somewhat inconsistent. Overall a good game. With some polishing and graphics it could be a great game!
