I'm really enjoying this game so far besides the super dark lighting. I was just wondering if there's any weapon upgrades I should avoid. So far I upgraded to the magnum and the mana leeching ax.

The ones that add fire damage tend to be underwhelming compared to their alternatives, especially if you're investing heavily in capacity. Fire damage is great [it lets you skip phases on a lot of enemies that go through forms as you damage them/have multiple health bars] but the other modes are a lot more useful. The autoturret is very cool, not actually that good or easy to use. The proximity grenade seems a little buggy and isn't nearly as strong or useful as the frag, and the slugs for the regular shotgun remain extremely useful long past where the autoloader shotgun will have become something you accidentally switch to. Nothing you pick will outright ruin your game, but I do wish you could change which one you picked.

Also try running medium graphics settings instead of high, there's apparently some problems still with how overly dark High makes it.

I turned my graphics down to low and i think it's better than medium as far as darkness goes.

There is brightness slider in the graphic options. You can also probably tweak brightness from your graphics card software, not to mention the monitor :D If you don't want to touch any of these, you may add some noise in the custom shader menu, for example 0.3 is not that noticeable, but makes the whole screen a bit brighter.

Regarding upgrades, I would ignore axe, staff, dynamite and crossbow altogether. Double smgs reduce accuracy so much that it makes them useless even on medium distance. Slug shotgun seems much more practical than autoloader.

And I would disagree that fire things are underwhelming. Fiery double barreled shotgun is ridiculously powerful if you shoot like 3-4 times and let enemies burn for a while. Not only they skip injured stages, so you only have to kill them once, but also seems to prevent them from attacking sometimes. Also, fire damage over time stacks. Fire lance is a beast as well.

Spells except freeze are mostly useless.

The fire weapons are by no means useless, and they probably have a better total damage/ammo use if you're allowing the damage over time to do its job, but for a game with this pace, it felt less useful than just being able to outright gib a bunch of stuff and move on. Plus freeze is only the second most powerful spell imo, after the ammo summon spell which completely breaks the last two episodes

I want some nutzo NG+ mode that lets you get double upgraded weapons. How Cool would that be?

A Boomstick with eigh barrles that fire four at a time or a magnum flare pistol would both be of the hook, chain, hiz houz and the scales.

Personaly I really love the Flamelance. Sure it eats ammo like so sort of fuel-eating machine but watching pretty much anything turn to dust in less than a second feels soo guud.

Thats a very good Idea, if not mixed weapons at least a way to change them with a key. More options are always good. And why not give us double or triple ammo and give more hp to the enemies. just for balance purposes.

I second avoiding the crossbow upgrades, and for the staff, I would argue that the lighting version is pretty good (I beat Hardcore with it). I'm using the ice version of the staff in my current run, and though it's nice to gib one of those buff Anubis guys in one hit, I find it uses too much mana to be worth it (more than you can get back with the souls perk, unlike the lightning staff).

Swapping upgrades is another interesting idea.

You could combine our idea by giving weapons three modes: Upgrade 1,Upgrade 2 and a combined/super mode. If you wanna balance is give it an extra high ammo cost or have it cost mana to keep active.

Yep, but at the moment we can only dream, we dont know if dev want to add thos sort of things to the game or if he take that into consideration. Even when probably will give more life to the game

In terms of balance if the weapons are op, I prefere raise hp on enemies. Its boring when a weapon waste the ammo faster or mana. Its an arcade shooter, so I like to shoot and pray sometimes.
