Fun fights with a light (heavy later on) bullet hell aspect to them. World that is so open there is an achievement for a 0% Run. Multiple difficulty levels that really fucking ramp up that bullet hell aspect if that's what you want. Another character for pretty cheap that plays completely differently for variety (Bosses don't change much admittedly, it's more Richter Mode in design than another campaign). Cute character designs. Good music. Highly recommended by Christ Centered Gamer (the only good game review site). Often pretty cheap on sale. It's a great game.
The sequel is much more so-so since it was written and drawn by somebody else. Gameplay is okay (in some aspects better) since it's by the RR guys but the world suffers for the story.
