Awesome / Wayward Souls

• Beating catacombs the first time makes you feel awesome, seriously.
• The Bearer. A Bullet Hell boss as the final boss? Yes please! {Though it becomes anticlimactic if you have hourglasses)
• Beating Last Crusade, the Paladin's special campaign. After seeing your playable characters getting essentially driven mad, and after fighting against tons of mobs with little health recovery, its very satisfying when you finally beat Aloysius and end the curse, finally ending the curse and giving the game True Ending.
