I'm glad you're enjoying the game so far! You're right that it is quite difficult at the moment. It will be rebalanced to be less difficult in the future (or at least have a less difficult mode). There are some players in our discord who can beat the game consistently so if you want to hop in there I'm sure they'd be happy to give you advice but I completely understand if you'd rather come back later when the game is less difficult.
Are there other aspects of the game that you're wishing were more polished besides the difficulty?
