After 8 hours in multiplayer me and my friends really like the game, but there are several things of concern
Screen Clutter (Multiplayer Visual Effects)
In multiplayer, the number of effects on screen, especially from certain skills, makes it very difficult to see what is happening. It would help a lot to have an option to reduce visual effects, and ideally the ability to completely disable ally effects.
Mage Dodge (Balance Concern)
Currently, the mage only has one dodge, which feels unbalanced compared to other classes. Since many bosses use rapid fire red circle attacks, this feels especially punishing for the mage. I recommend giving the mage a second dodge in line with other classes to make the experience fairer.
Curses (Reward vs. Risk)
Curses do not feel rewarding at the moment. In my runs, my group always chooses the worst curse, but the rewards rarely feel worth it. Often the drops just get turned into dust. A possible improvement would be to show the reward before selecting the curse. This way players can make an informed decision, choosing a harsher curse for a better reward with full knowledge of the risk and reward tradeoff, instead of it feeling like pure RNG.
Essence Combining (Clarity for New Players)
When you pick up an essence you already own, it combines automatically. This is not explained clearly, and for new players it looks like the item just disappears. A prompt asking if you would like to pick it up and combine it, or leave it to share with teammates, would both reduce confusion and add a layer of teamwork.
Unexplained Red Circles Around Characters
Sometimes red circles appear around characters without clear explanation. For example, I discovered one was tied to an essence that increases damage taken by nearby enemies, but another source remained a mystery. If items or abilities create these effects, they should be clearly explained in the item text to avoid confusion.
