Mostly frustrating. Good strategy game but bad luck/die roll can totally destroy any good strategy . Alot of grinding to get gold to do any decent upgrades, and definitely needs more holding space for chests, which limits basic challenge or continuous play. Once you reach higher levels, computer sabotages wins so very few, really discouraging further play. New monster collaboration is fun, but again, low win capability. Could be fun, but don't get too invested
