The update is fun and brings new elements into the game but there are still some annoying mechanics :
-Make an essence sink, possibly have some character upgrades or skills to unlock with them
-Gambler has no counter if you fight him at the beginning of the game, a few cheap very basic skill could help and introduce mechanics to the player.
-A small suggestion is to have a risk of rain esque system when on the planet, then there is some added pressure and the old ost can be reused as higher difficulties are reached slowly adding more parts of it.
