Easiest way to get the impossible badge: go through The Tower with the Wizard class while having the 'Classicist' perk (Uses a single mana bar for all magic spells) and 'Soulmancer' gear (Start with the extra spell 'Form Wisp') as your active effects. Slowly build an army of wisps, focusing your talent points on maximizing firebolt damage (make sure to purchase the 'Inspire' talent ASAP as well.) First time I did this I got 74,000 points. Second time I got 143,000 points, well over the necessary amount for the impossible badge.
Fun game, but boss rush is ridiculous. I spent an hour and a half getting every heart + spiral... I feel like I should be able to use them in boss rush somehow. Credits should also be skippable, I don't need to see every enemy in the game...
Thank you for trying Crusaders. We understand that clicker/incremental games won't be for everyone.
