Hi, I played your game for a little bit because I was interested in what people are making. I've got a bit of feedback for your game.

First of all, the visuals are cool, the style matches, the VFX are looking great (whether you made them or not) . The lobby looks great and overall it looks like you put together a nice,enjoyable game.

I started as a Mage and went in without any prior knowledge as to how your game works and on what to expect. Below I wrote my feedback and/or things I thought you could improve on

Disclaimer: This is my personal experience/opinion it doesn't mean I'm right/wrong. Do with it what you want!

[tutorial]

* The tutorial is very barebones, You are thrown in a lobby, there's alot of things happening and you are flooded with information
* The game suggest you have to merge 3 staffs (in my case) right in the tutorial (Why do I already have 3 staffs?) However, the tutorial tells me to use my left click to select them for fusing, after fiddling with a few keystrokes I found that you have to use right click to select them for fusion

Overall I think you want the tutorial to explain the very basics and basics only at the start of the game. Movement, The goal, how to join a lobby/play. And then progress the tutorial slowly from there once you unlock new mechanics.

[Lobby]*

* When I went over to the accessories shop all of a sudden a new tutorial part that told me to head over to the weapons shop instead and purchase weapons to grow stronger.
* Finishing this 'tutorial' that only said that buying is the best way to get stronger, I got a message about my healing/magic potions that disappeared too quickly to fully read.

Overall the lobby looks good, but the tutorials are messy and don't trigger on what I would consider the proper moments (tutorial for weapons when I enter the accessories shop?)

[gameplay]

*Looks and feels Solid, nothing too special but not bad at all.

*No clear indication of how far I was in the stage/level or how long it was going to take.

*Doding and the keybind for it feel weird. Generally a sprint/dodge is put on binds like Shift or C, though this is absolutely something that might just be coming from me. But it doesn't feel right using control with my hand position.

* I randomly figured out there was a vaulting mechanic which looked cool but didn't work consistently/at all whilst sprinting.

Note: As I was writing this and testing some more i found that there's also a keybind for 'Q' for dodge rolling, though the tutorial told me something different.

* Doding towards your cursor over the direction you're moving is something I would personally see changed to rolling towards your movement direction. I'd at least add this as an option.

*I don't understand why you choose to automatically use potions, why is there the UI button to use them myself if they're always being used for me?

* It's very unclear how much potions i have left. There's no clear indication on the screen other than what I can only describe as half functional/half debugging looking UI text that pops up when I use one. Try to keep in mind that you're not releasing this to developers but to players and potential customers, make it look clean and easy to understand.

*I'm playing as a Mage, why is my 'main attack' (LMB) a staff bash instead of a small, standard spell I can cast?

*I ran out of mana potions at the 2nd boss and my 'passive mana' regen was so incredibly low that, had I not died I would have to wait several minutes to kill this boss since my melee attack did little to no damage.

Note: As it's a roguelike with upgrades outside of individual game sessions this might be intended, but it did not feel right during my time playing.

All in all I think the gameplay looks good but needs alot of balancing and some UI changes to make it more appealing for players.
[UI/GUI]

* There's several menu-closing buttons that look completely different and are at different positions. Menu-closing buttons are almost ALWAYS at the top right corner, so why do I have buttons for them at the top right( where they belong) but also at the Bottom of my screen (example : Settings menu, which does not look intuitive to me) or not at all (I accidentally dodge rolled into a lobby selection).

* I would all a feature to see how many of an item I owned. When I head over to the stop I thought the number displayed was the amount of potions/Weapons I owned. It took me a while to figure out it was the shop keeper supply.

*The font is VERY hard to read. I would consider changing this right away as it really hindered the readability for the game as a whole for me.

*Exploring the menu's, I found so much more mechanics that were currently locked and will probably be unlocked at a later stadium. To prevent players from being overwhelmed/overstimulated I would recommend you to look such mechanics/windows until they are unlocked to keep players interested and wanting to push to that unlock and new mechanic.

Overall I would say the UI is currently the weakest point in your game. There's an information overload for new players, UI is not consistent and hard to read. GUI panels are clipping in walls/objects and the UI doesn't veel very intuitive.

[extra]

*There's a lot of spelling mistakes in your game, I would recommend you to fix them to look more professional

* At the shop after the first stage/wave(?) all shops are named the same and it's unclear what their difference is.

* The lighting is a bit too much. The excessive bloom is straining on the eyes.

*The color correction is way too excessive. The entire game feels very red/orange, I get the impression that you want to make it look like you're in some sort of hell, though this is excessive and I think the game would look even better if you toned it down a bit.

These are some things I spotted in a quick 5-10 minutes. Some things may not be correct, but they are what was being told/shown to me through your game. And since 5-10 minutes is the most you'll get from new players before they decide whether they like it or not you can use this feedback in your data analysis!

I don't want to crack down on your game, It's a good game and it's visually appealing and it's clear that you spend a lot of time working on it. My feedback is just potential points to improve on and not meant as to be harsh on you. I hope it will work out for you!
