Wow okay this game is crunchy for sure, like cool crunchy like a taco but regardless crunchy.  First off a few questions I got, why is there a notepad system for this game? Why is there a rotating display launcher system that opens the new scenes in a new window? Why when I start the game do I get another window showing me all these stats wouldnt you just have the game in one window one scene and then load the next scene instead and render stats on a togglable tab button or something?

Alright that's enough questions here's my thoughts on what I liked/wanted changes for:

Fun/Gameplay:

I'm not sure id call this game fun but I definitely wouldn't call it boring if anything I might say that this game lacks substance or has pacing issues other than not fun.  From what I can tell the gameplay loop is that you spawn in and explore a pseudo randomly generated dungeon (well done on this btw looks like you took tiles and made the map generate off of those I think) and look around for the nearest wizard to kill you (most likely) of which there were only two types I managed to see because of how much I suck at this game being the red wizard and blue wizard. From the games screenshots it looks like there is more wizards to end my run but I never got far enough to see them which could either fall on the game is too difficult for a casual player or I just really suck at games. Both could be totally true so all id say is rebalancing the games combat system would be an important thing to look at for future builds. As per the many comments on this game It looks like some wizards need a nerf of which I agree. I also think bullet size needs a nerf as they seem about 50% too large.  its up to you to make those changes and see how your player base feels about them to really nail down that good feeling while playing the game. 

The blue wizard insta-killed me but I'm not too worried as this is just a jam build balancing of a game is hard when you are the only person looking at it.

I see a lot of comments here abut how you should add a ranged attack and honestly I tend to disagree, and here's why:

Being up close and dodging bullets is sick and considering from what else ive read is that this plugin you use (you 100% do not need to use plugins and can code bullet logic yourself in Godot) doesn't allow it why not instead allow the player to parry the projectile back at the enemy. Replace the wifi attack or whatever it is supposed to be and throw in a sword asset that you swing on hit. If you perfect parry the bullet gets reflected back and poof problem solved. As for it needing a target you could totally just ray cast it (https://docs.godotengine.org/en/stable/tutorials/physics/ray-casting.html) with its current velocity and throw some logic on there that if it hits an enemy it does some damage or whatever. Again I am unsure how this plugin works and I wrote my own bullet logic (my bullets don't function anything like yours so maybe its more complicated for you) 

Visual:

This game is pretty pixelated which is fine the art here is nothing to write home about but its not some terrible quick drawing I can tell you spent some time on the assets used for the game.  Style wise this game totally has an identity crisis. The menus look like a completely different game in comparison to the actual game. I cant place the menu slider thing I'm looking at but it does have a retro feel, however the idea that its all bright and blue where as the game is dark and dungeony so there is some visual clash.  In terms of actually being in game the tiny cobblestones or bricks or  whatever feel a bit too small  for easier readability but I'm not one to judge my tile set consisted of one boring tile so this is still a plus but might need some small tweaks for sure.  Also the dungeons feel a bit disconnected with the sprites for the wizards. The wizard sprites are fine I just think they need to match their environment a bit more, kind of like if you color grade a video so the colors don't look off the same needs to happen here. Since the general theme of these dungeons is kind of muted it might be a good idea to desaturate some of the colors of the wizards and see if that still causes visual clash. Another thing I wanted to point out is that dungeons feel pretty empty other than enemies maybe I didn't get far enough or see enough but maybe some ground clutter or dead wizards or something could really sell that you are in a dungeon.

I want to touch on the whole opening a new window thing, and to be frank it feels like you discovered it was a feature in Godot and wrapped your game around including it as many times as you can. I'm not against opening a new window but consider how its used and does it really aid player experience? I think the best example of opening more windows as a feature that is well executed is how oneshot does this by making their puzzle based around this new borderless window piece of paper that interacts with the main game see screenshot below:

So to wrap up opening new windows in the game feels unnecessary in its current state when you could just load the scenes in a chain or loop.  main menu -> main game -> fail/win screen -> back to main menu 

If it is a feature you do really like you need to learn how to optimize the loading time so players stop complaining about it, or not whatever its a jam build.

Audio:

I feel like the music in the main menu is far too repetitive of a chord progression if that is even the case I'm not much a music person so I cant exactly tell other than its just too repetitive/simple to be interesting enough for me. 

Theme:

While this game is for sure a bullet hell im not sure if it has consequences per say but then again I didn't get very far into the game so maybe I just missed it, and for that reason I don't have much to say here.

Overall:

Itemfinity is a neat idea on a traditional bullet hell game mixed in with some rougelike dungeons. Nothing it does past its menu system and constant opening of windows is really shining as a cool mechanic or brings others to say "You got to play this game because of xyz feature" However given the time frame of this jam and what this game came out to be id say you did a decent enough job of adding features and making a solid game that functions which you can be proud of.  I hope none of this feedback comes off as too harsh or mean which is not my intent whatsoever I think the fact you made a submission is beyond good.

It's a cool concept the creativity is there but man this game really needs some tinkering under the hood because the performance is pretty bad. Everytime a new window comes up the game takes a painful pause until it loads, and I have a pretty good PC. You could've definitely had the launcher and windows be made in-engine/game and the performance would be way better and probably way easier to manage. The concept of only having close attacks for bullet hell enemies is cool but player attacks really need fine tuning also because it was really hard to actually make it connect to what you're trying to attack. Otherwise the game looks cool and other than needing polish its neat.

Very Interesting Game tbh, here is my feedback:
-The Main menu is one of the most creative ones i have ever seen, and it really caught my attention so really good job on this point.
- I also loved the system of the stats and the idea of having the stats in a different menu.
-The Art style , the music, and the SFX are really decent
-I believe that you have to work more on the fairness of the game, For instance if the player has encountered either the blue or the yellow enemy, The player is guaranteed to be hit regardless, in other words it doesn't give the player a chance (the slow time feature wouldn't help much),  while on the other hands some enemies are rather surprisingly easy like the green one.
-I also didn't like that the melee attack was very range-shorted and i have to almost stick to the enemy to damage it
-Good job also on the procedural generated dungeon !

Looking forward for future updates !!
