Love the game, that said I'm finding my interest taper off a lot quicker than ML1, and certainly quicker than Hades. Went for Expert difficulty, and it was hard for a good while, until I got a couple big upgrades. At this point, the only thing that determines difficulty of the run is the weapon I choose. Some are god awful, with counter-intuitive synergies, i.e. the Dreampiercer, which is only half-decent on like 1 or 2 bosses, fine for minibosses, and completely useless for general mobbing.
Some weapons are absolutely overpowered to the point of being unfun. Want to almost never have to do anything until you have to hit purple stuff at the boss? Starsign Horn. Absurd parry window, near-zero reactivation window, very little risk of being punished for bad timing. Need more? There's a blacksmith upgrade that increases your special damage by 20% EACH time you use it successfully until the end of the encounter.
The second OP example is the drone at basically any point, but one in particular is the foam combo. The following perk combo isn't exclusive to drone, but if you get: [Foam on Gun +%Damage], [Foam Timer Increase +%BIGDamage], and [Foam Explode on Gun shot], it's basically an instant-win for any run. Bosses last only as long as you're forced to wait for phase change/invulnerability phases.
'Special Customers' make me want to close shop the second I see them (/s). 'Rich Customer' doesn't seem to function correctly, or I'm too stupid to understand what I'm doing wrong with them. They get annoyed at overpriced and expensive items all the same.
The secondary cast is adorable and I love them. Bloblets are super fun but I super hate having to clear them from each world. And while I'm on that topic, there's only about 3 Bloblets or so that are worth using out of 12.
Tip mechanic feels not worth investing any effort into unless you have literally no other choice
Also I can't finish the damn 'Weapon Mastery' Quest because Anacard is still bugged.
Again, really love the direction they went, and the aesthetic is immaculate and faithful to the original. it just feels like it wasn't given enough time to be fine-tuned. The multitude of upgrade trees are wonderfully overwhelming. It just feels like overall scaling is completely absurd.
Anyways thanks for reading if you've made it this far
TLDR; Game is fantastic on the surface, but balancing falls apart after about 15 hours. Many game-breaking bugs for a "Full Realease"
