Very very cool. Well done! I usually don't like the healing tome and the invulnerability because they get rid of the already very useful active abilities monsters have, but I see you gave them to Chikia and Gora, who have useful abilities but sometimes not as much useful as the others. It's a good strat and two very nice merged items!
Last time the candy record for infinite mode was 51. Is it your 60 now? :D
