I've finally started playing the game on PC after having it sit on my backlog forever, and I've got to say I had a pretty rough time with the lava area boss as Hugo until I decided to go back and grind a couple levels, but even though the boss was a cakewalk after the grind, the enemies in the sand area were constantly taking 1-3 damage per attack (except for mages taking around 15), which made beating the red worms a chore (god damn respawning goat skeletons!), and then I came across four red bomb-flinging enemies that I just can't kill because all my attacks and abilities deal only 1 damage per hit. Since I'd rather not grind even more levels (it was mind-numbing, really), I think I'll have to just start a new savefil or something, since I feel like I'm really stuck and the alternative is to bore myself to death to stand a chance against the normal enemies in the new area.
Personally, I'd say the level design is guilty of being awfully linear, and how it tends to rely on finding "secrets" to actually progress through the main path, making those apparently optional places mandatory. For example, once I figured I was stuck at the sand level unless I ground even more levels, I decided to go back and comb through each previous area with the mask that allows you to access special pathways, and was really let down when I realized that it was just a boring item you were meant to use at places with those red marks only (at least AFAIK). There probably are some optional places I haven't found yet (I saw a gameplay video where the player had a level 4 weapon when fighting the lava boss, so I guess I just missed the ore somewhere), but I don't rally feel that compelled to keep looking, anyway.
Having to constantly access the menu to use/equip items is often more busywork than anything, and reminds me of how boring it was in OoT to constantly equip and unequip those blasted iron boots. I had to go all over the first area because I didn't know I was actually supposed to equip Ricco's pendant as opposed to it being just a key item used for doing a flag check, and a similar thing happened when I saw a cracked pipe in the lava area and tried to bomb it, only to get told by the game that I wasn't supposed to bomb that one weak structure, but rather look for a key item (that I obviously had to use from the menu, yay!). Warping being mapped to an usable item as opposed to simply allowing you to do that while examining a godess statue also felt really off... all in all, I fear the game's user experience leaves an awful lot to be desired.
Also, having played through a bit of Oath before, I'd also feel inclined to agree that Hugo's ranged attacks are an ill fit for this kind of game. Using him makes most melee enemies into a joke, and even enemies with ranged attacks aren't all that bad since you often get to fight them on even footing as opposed to being a melee character.
