I looked over your devlog and it seems like this is still pretty early in development still, but there's a solid foundation to build on. Your main character seems to be a duck with an eyepatch. This is a fun design. Perhaps you could lean into the duck design a bit more? Assuming that is what they are supposed to be. It could help give the game a stronger identity.

What is the blue meter for? I wasn't sure if I was missing something or it just hasn't been programmed in yet. Like Kwarven said, I, too, didn't encounter any chests in my playthrough like the description mentioned. I also wasn't sure what I needed to do or how I could get more ammo once I was out. There wasn't a clear objective.

I think the player's move speed could be increased a bit. They feel too slow, even with the dash. Speaking of which, I think dash being bound to Space key would be more comfortable than having it on C key. Improving the movement could help with responding to enemies easier and make navigating the dungeon more engaging.

You mentioned you changed the title from Maze Shooter to Dungeon Shooter. I imagine these are prototype titles. I would suggest a name change as these don't stand out too well. They seem more like genre tags than game titles. Overall, I would encourage you to think about what would make your game stand out from others in your genre. Based on what I saw in your devlog, it seems you have a pretty good idea of what elements you need to implement to get a functional game loop, but there wasn't anything in the prototype or devlog that made me think "Oh, I want to play this over other dungeon-based shooters."

With that said, nice work so far. I hope my feedback is helpful to you. I think focusing on clarity and a solid identity/hook for your game will really help this project stand out.

This game reminded me a bit of Enter the Gungeon, but with an emphasis on enemies that roll right into you instead of just shooting. Really enjoy this kind of gameplay, the only thing that made the game a bit difficult to get into was not having any explicit objective, like finding an item, room, etc. Also, I didn't end up seeing any chests during my playthroughs, maybe just unlucky?

Looking forward to seeing any potential updates!

Great gob! This turtles are so hard to kill :D

Overall I didn't catch any bugs but I have some wishes for your game.
1. Sounds in your game and some background music. 
2. Maybe healthbar for enemies.
3. More varity of enemies in future.
4. I didn't understand how is reload works. Wish some animation or sound design for it.

Good start for a good game! Hope you will try our game too. Wish you all the best in your development!
