One thing that always gets me about this game is to choose the shadow or the traveler. the shadow has the better weapon, but less health. Love this game. it really makes you think. would be cool if after defeating bosses could play as them.
honestly i love controlling space with Ronin. you just need a way to hit ranged foes with 5 hp for a big chunk of damage so i usually take at least +1 on the spear, traps and hooks are helpful as well. I have yet to get good with assassin, but the super short-cooldown slash is very helpful and an easy upgrade target, all you need is range and/or a multihit like the spear or arrow, and you're largely fine.
